Adsorption process both in post carbon dioxide capture and wastewater treatment has been receiving widespread attention over the past decades as a mitigating technology for climate change and water pollution, respectively. With this increasing interest in adsorption processes to address environmental concerns, development of an adsorbent with not just high adsorptive capacity but which is also low cost is of great interest among researchers. In this study, an agricultural waste which was already utilized as a boiler fuel in a paper industry was investigated for its potential as an adsorbent for both carbon dioxide capture and wastewater treatment. Specifically, the CO2 and methylene blue adsorption capacity of carbon residue from rice husk used as boiler fuel was determined and was compared with a biochar synthesized from rice husk. Furthermore, Scanning Electron Microscope (SEM) and Thermogravimetric analysis (TGA) were used for the characterization of the adsorbents. Results showed that the carbon residue can be a potential adsorbent for both applications with about 0.5 wt% CO2 adsorption and 100% removal of the methylene blue.

Porosity Characterization

Eggshells and rice husk, two types of notable agricultural waste were used as bioadsorbent to remove Methylene Blue dye (MBD) in aqueous solution. This study was to investigate the performance of these two bioadsorbents in removing MBD. The removal percentage, adsorption capacity, and porosity characterization were examined. The method applied was a physical filtration. UV-VIS Spectrophotometer was used to determine the efficiency of the bioadsorbents in MBD adsorption. The highest removal percentage at the most concentrated MBD were 51% and 98% for eggshells and rice husks respectively. Meanwhile the characterization of rice husks pore size and volume proves that higher adsorptivity towards dye compares to eggshells porosity. It was concluded that the eggshells and rice husks bioadsorbents was successful to treat industrial textile wastewater with rice husks as the most efficient bioadsorbent in removing MBD.

Sorbent Materials

In this work carbonized rice husk  was used as carbon-based solid matrix in the preparation of composite materials modified with Fe3O4 particles. Aim of this study is to exploit the advantages and shortcomings of using a real biomass as starting material for the preparation of sorbents for CO2 capture applications. Sorption capacity of the obtained composite materials was tested on fixed-bed  microreactor.

Isotherm And Kinetic Models

This study discusses the development of Indonesian natural zeolite and agricultural waste i.e bagasse ash and rice husk ash as natural adsorbents. These materials were used as an adsorbent for methyl orange and methylene blue adsorption for isotherm and kinetic study. Adsorption kinetic models for methyl orange and methylene blue with all adsorbents were a pseudo-second-order except methyl orange adsorption with bagasse ash adsorbent (MA) that followed pseudo-first-order. Isotherm models for all adsorption experiments were Langmuir type except methyl orange adsorption using rice husk adsorbent (MS) that followed Freundlich type.

A series of activated carbons ‘Z’ was prepared from Aleppo Pistacia Vera shells using different percentages of zinc chloride at 873 K in the absence of air. Another series ‘ZN’ was prepared using the same conditions as for the ‘Z’ series but employing a nitrogen atmosphere to effect carbonization. The textural properties of the two series of samples were determined from the adsorption of carbon dioxide and methylene blue at 298 K. Activated carbons with a high adsorptive capacity for methylene blue were obtained. Activation with zinc chloride proceeded with increasing microporosity via the creation of new micropores. At high percentages of zinc chloride, slight partial pore widening may take place. Carbon dioxide was accessible to the entire pore system and was therefore suitable as a probe for the investigation of the textural properties of the activated carbons studied. A fraction of the porosity was inaccessible to methylene blue molecules and consequently lower surface areas were calculated from the adsorption of this dye molecule.
