Adsorption of Cr(VI) from wastewater by iron-modified coconut shell biochar
نویسندگان
چکیده
This study is aimed to investigate the effect of raw and Fe-modified coconut shell biochar on adsorption Cr(VI) in wastewater. was obtained from impregnation with FeNO3 solutions surface functional groups two biochars were examined by infrared spectrometer.The result showed that had lower abundance than biochar, group Fe-O.The removal rate increased 94.89% compared because existing Fe-O . The modified could reach more 99.0% when concentration 12μg/ mL, pH 4.0, adsorbent dosage 0.2g time 2h.

Adsorption Process for Wastewater Treatment by using Coconut Shell
Adsorption of heavy metal on the solid surfaces is an important technique to remove them from the industrial wastewaters. The purpose of the present study is to evaluate the ability of agro-waste material coconut shell to remove Cr (VI) from wastewater. The extant of removal was found to be dependent on pH, contact time, adsorbent dose, concentration of metal and particle size. The adsorption f...

متن کاملAdsorption of Lead from Aqueous Solution by Modified Beech Sawdust
Sawdust is now being investigated as an adsorbent to remove contaminants from aqueous solution. Heavy metals can be decreased very effectively with the organic material. In this research, adsorption of Pb (II) onto modified beech sawdust in a batch system was investigated. Sawdust was collected from timber mill of Qom, Iran, and modified with H2SO4 and NaOH. Then, the effe...
