摘要
The potential of carbonized spent bleaching earth (CSBE) to remove/reduce acid and basic dyes in aqueous solution was investigated. Results show that CSBE was more effective in removing basic dyes. Parameters like pH initial concentration, agitation rate, contact time and temperature which affect the sorption process were studied As determined from Langmuir isotherms the maximum sorption capacities of CSBE for Basic Blue 3 and Methylene Blue were 102.6 and 94.5 mg/g respectively Hence CSBE could be a useful sorbent in the treatment of baisc dyes in wastewater.
