Removal of herbicides mixture of atrazine, metribuzin, metolachlor and alachlor from water using granular carbon
INDIAN JOURNAL OF CHEMICAL TECHNOLOGY(2017)
摘要
Removal of atrazine, metribuzin, metolachlor and alachlor in mixture at 5 mu g mL(-1) fortification level on granular carbon has been studied using batch method. Metribuzin is found to be the most adsorbed herbicide and adsorption followed the order: metribuzin> atrazine> alachlor> metolachlor. Desorption results suggest that atrazine and metribuzin are bound irreversibly while metolachlor and alachlor are desorbed and percent desorption of alachlor (1.28%) is more than metolachlor (1.14%). Column studies using granular carbon have been carried out at fortification level of 5, 1 and 0.1 mu g mL(-1). At higher concentration (1 and 5 mu g mL(-1)), metolachlor is least sorbed and sorption followed order: metolachlor>alachlor> atrazine>metribuzin but, at lower concentration (0.1 mu g mL(-1)), alachlor is the least adsorbed herbicide. The performance of horizontal column is found better than the vertical column.
