Heavy Metal Compound

The purpose of this research is  to study the potency of chitosan synthesis of shrimp shells from Bintuni as a biosorbent of organic compound and heavy metal compound. The main procedure of chitosan synthesis is completed by insulating chitin from shrimp shells and then chitin is deacetilated to transform chitin to be chitosan. The wastewater were characterized to know the concentration of Total Organic Carbon (TOC), fat oil, and Zinc metal and studied the adsorption of each compound at 0,1; 0,5; 1; 2g  dosage chitosan.  Adsorption study result showed that chitosan can adsorb the fuel oil and Zinc metal which contained in wastewater. However, it was not adsorb the TOC compound. The yield of chitosan is 46,88%. Increasing the chitosan by up to 2 g resulted  in the creasing of the adsorption effectiveness up to 99,09% for the fuel oil and 69,28%  for Zinc. The maximum chitosan adsorption capacity accomplished at 0,1gram  chitosan in 100 mL wastewater.

This article describes a pilot test at a sewage sludge incineration plant and shows its results considering the impacts of reducing the minimum combustion temperature from 850°C to 800°C. The lowering leads to an actual reduction of the average combustion temperature by 25 K and a significant reduction in the fuel oil consumption for support firing. The test shall be used for providing evidence that the changed combustion conditions do not result in higher air pollutant emissions. The analysis focusses on the effects of the combustion temperature on nitrogen oxides (NOx) and total organic carbon emissions. The evaluation of all continuously monitored emissions shows reduced emission levels compared to the previous years, especially for NOx.

The Impact

Assessment of treated wastewater produced from Al-Lajoun collection tanks of the wastewater treatment plant in Karak province was carried out in term of physical properties, its major ionic composition, heavy metals and general organic content, for both wastewater influent and effluent. Sampling was done in two periods during (2005-2006) summer season and during winter season to detect the impact of climate on treated wastewater quality. Soil samples were collected from Al-Lajoun valley where the treated wastewater drained, to determine the heavy metal and total organic carbon concentrations at same time. The study showed that the treated wastewater was low in its heavy metals contents during both winter and summer seasons, which was attributed to high pH value enhancing their precipitations. Some of the major ions such as Cl-, Na+, HCO33-, Mg2+in addition to biological oxygen demand and chemical oxygen demand were higher than the recommended Jordanian guidelines for drained water in valleys. The treated wastewater contained some organic compounds of toxic type such as polycyclic aromatic hydrocarbons. Results showed that the soil was low in its heavy metal contents and total organic carbon with distance from the discharging pond, which attributed to the adsorption of heavy metals, total organic carbon and sedimentation of suspended particulates. From this study it was concluded that the treated wastewater must be used in situ for production of animal fodder and prohibit its contact with the surface and groundwater resources of the area specially Al-Mujeb dam where it is collected.

Currently, the Irati Formation, in Paraná Basin, Brazil, represents one of the world's largest reserves of oil shale. Among the shale-derived products stands out the fuel oil, gas, naphtha, fuel, liquefied gas, and sulfur, in addition to byproducts that can be used by the asphalt, cement, agricultural, and ceramics industries. This study describes and illustrates features of organic-rich shales of the Lower Permian Assistência Member, Irati Formation, scanning electron microscopy (SEM) was combined with energy-dispersive x-ray spectrometric (EDS), x-ray diffraction (XRD), total organic carbon (TOC), total sulfur (S), insoluble residue (IR) and Rock-Eval pyrolysis to characterize the mineral composition, organic matter distribution and different types of pore at the micrometer scale. These analyses were performed on samples from well SP-32-PR located in the Sapopema township, Northeast Paraná State, in South of Brazil. The investigations demonstrated that the Assistance Member has high total organic carbon (TOC) content, generation potential (S2) and hydrogen index (HI), but is in an immature stage. The mineralogical content of the Assistência Member presents intervals rich in quartz, plagioclase, carbonates and clay minerals. Pores distribution includes intraparticle within organic matter and interparticle pores in pyrite framboids, surrounding quartz grains and between organic matter and mineral grains. ResumoAtualmente, a Formação Irati, na Bacia do Paraná, no Brasil, representa uma das maiores reservas mundiais de Petróleo de xisto. Entre os produtos derivados do xisto, destacam-se o óleo combustível, gás, nafta, combustível, gás liquefeito e enxofre, além de subprodutos que podem ser utilizados pelas indústrias de asfalto, cimento, agricultura e cerâmica. Este estudo descreve e ilustra características de xistos ricos em matéria orgânica do Membro Permiano Inferior Assistência, Formação Irati. Microscopia eletrônica de varredura (SEM) foi combinada com Espectrometria de Raios-X de energia dispersiva (EDS), Difração de Raios-X (XRD), carbono orgânico total (COT), enxofre total (S), resíduo insolúvel (IV) e pirólise Rock-Eval para a caracterização da composição mineral, distribuição da matéria orgânica e diferentes tipos de poros à escala micrométrica. Essas análises foram realizadas em amostras do poço SP-32-PR localizadas no município de Sapopema, no nordeste do Paraná, no sul do Brasil. As investigações demonstraram que o Membro de Assistência possui elevado teor de carbono orgânico total (TOC), potencial de geração (S2) e índice de hidrogênio (HI), mas está em um estágio imaturo. O conteúdo mineralógico do Membro Assistência apresenta intervalos ricos em quartzo, plagioclásio, carbonatos e minerais argilosos. A distribuição dos poros inclui intra-partículas na matéria orgânica e poros inter-partículas em framboides de pirita, nos grãos de quartzo circundantes e na matéria orgânica e noutros grãos minerais.

<p>Penelitian ini bertujuan untuk menentukan senyawa organik khususnya organic karbon terlarut (DOC) dari dua spesies daun tumbuhan (<em>wandoo eucalyptus </em>and <em>pinus radiate, conifer</em>) yang larut dalam air selama periode 5 bulan leaching eksperimen. Kecepatan melarutnya senyawa organic ditentukan secara kuantitatif dan kualitatif menggunakan kombinasi dari beberapa teknik diantaranya Total Organic Carbon (TOC) analyser, Ultraviolet-Visible (UV-VIS) spektrokopi dan pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS).</p><p>Hasil analisis DOC dan UV menunjukkan peningkatan yang tajam dari kelarutan senyawa organic di awal periode pengamatan yang selanjutnya berkurang seiring dengan waktu secara eksponensial. Jumlah relatif senyawa organic yang terlarut tergantung pada luas permukaan, aktifitas mikrobiologi dan jenis sampel tumbuhan (segar atau kering) yang digunakan. Fluktuasi profil DOC dan UV<sub>254</sub> disebabkan oleh aktifitas mikrobiologi. Diperoleh bahwa daun kering lebih mudah terdegradasi menghasilkan senyawa organic dalam air dibandingkan dengan daun segar. Hasil pyrolysis secara umum menunjukkan bahwa senyawa hidrokarbon aromatic dan fenol (dan turunannya) lebih banyak ditemukan pada residue sampel setelah proses leaching kemungkinan karena adanya senyawa lignin atau aktifitas humifikasi mikrobiologi membuktikan bahwa senyawa-senyawa tersebut merupakan komponen penting dalam proses karakterisasi DOC.</p>
