Abstract: The adsorption of crude oil from water by using Potassium hydroxide (KOH) prepared from coconut coir activated carbon CCAC_KOH was investigated by batch adsorption under varying parameters such as adsorbent dosage, contact time, initial oil concentration, temperature and agitation speed. The morphological modification significantly increased the hyd... Show More

Abstract: This study was carried out to evaluate the efficiency of metal ions removal from aqueous solution using silica adsorbent. Silica was extracted from rice husk using sol-gel method. The silica was modified with 1.0 M of nitric acid. Using batch adsorption technique, the effects of temperature, pH, contact time and adsorbent dosage on adsorption proce... Show More
