Study on the Adsorption of Trichloroethylene in Water on Activated Carbon and Activated Carbon Fibers

The removal of trichloroethylene (TCE) from water using activated carbon fibers (ACF) and activated carbon (AC) was investigated. Adsorption, as an efficient process to remove TCE from water was chosen; in particular with ACF and AC as adsorbents. The results showed that physisorption play important roles for adsorption of TCE onto activated carbon fibers, while the less important chemisorption. Langmuir and Freundlich models were then employed to correlate the equilibria data. The Langmuir model best described the AC adsorption isotherm of TCE, with R2 0.9942. Freundlich model best fitted the ACF adsorption isotherm of TCE, with R2 0.9978.

Telah dilakukan penelitian adsorpsi rhodamin B pada arang aktif yang dibuat dari kayu linggua. Penelitian ini bertujuan untuk menentukan koefisien adsorpsi arang aktif limbah gergajian kayu linggua terhadap zat warna rhodamin B dengan menggunakan isoterm adsorpsi Langmuir dan Freundlich. Penelitian dilakukan secara batch di mana 0,1; 0,2; 0,4; 0,7 dan 1 gram arang aktif dimasukkan ke dalam labu Erlenmeyer terpisah yang masing-masing telah berisi 100 mL larutan rhodamin B 100 ppm. Campuran kemudian diperlakukan di atas magnetic stirrer selama 50 menit dan selanjutnya konsentrasi larutan rhodamin B dianalisis menggunakan spektrofotometer UV-Vis. Hasil penelitian menunjukkan bahwa isoterm adsorpsi rhodamin B pada arang aktif kayu linggua lebih mengikuti isoterm adsorpsi Freundlich dengan koefisien adsorpsi 2,999x10-4 dan nilai intensitas adsorpsi 1,459.Adsorption isotherm of rhodamine B by activated carbon made from linggua wood waste was investigated. The adsorption isotherm was analyzed by Langmuir and Freundlich models. The isotherm was measured by batch experiment where 0,1; 0,2; 0,4; 0,7; and 1,0 grams where added into the separated Erlenmeyer flasks filled with 100 mL of 100 ppm rhodamine B. The mixtures were then treated on magnetic stirrers for 50 minutes followed by rhodamine B analysis using spectrophotometer UV-Vis. The result showed that the isotherm followed the Freundlich model better than Langmuir with the Freundlich adsorption coefficient of 2,999x10-4 and the Freundlich exponent of 1,459.

ABSTRACTPoly(acrylonitrile) fibers are used in the manufacture of activated carbon fibers, which are activated with phosphate groups for the removal of lead ions in aqueous solutions. Removal of lead ions is performed in a water bath at 30°C. Trough isotherm models of Langmuir and Freundlich analyzed the aqueous solution. Kinetic analysis is performed using the model pseudo-first and pseudo-second order. The result show that adsorption equilibrium is adjusted to the Freundlich model and the kinetic model of pseudo-second order led to the best fit correlation.

Activating Agent

Various jute-based activated carbon fibers were prepared by using jute fibers as raw materials and phosphoric acid as activating agent. The effects of three main factors such as concentration of activating agent, activation temperature and activation time on the yield and adsorptive properties of active carbon fibers were investigated via orthogonal experiments. The surface physical morphology of jute-based activated carbon fiber was also observed by using Scanning Electron Microscope. Results showed that the optimum conditions were phosphoric acid concentration of 4 mol/L, activation temperature of 600 °C and activation time of 1h. The yield, iodine number and amount of methylene blue adsorption of the active carbon fiber prepared under optimum conditions were 37.99 %, 1208.87 mg/g and 374.65 mg/g, respectively.
