Evaluation of economical sorbents for the removal of metolachlor from contaminated wastewater
MetadataShow full item record
This suggests that different bonding mechanisms may be involved for the sorption of unformulated and formulated metolachlor to the sorbents.
Various procedures were studied to improve removal efficiencies of formulated metolachlor. Sorption of metolachlor to peat was enhanced by hydrating the peat and pre-treating the peat with HCI. Circulation of formulated metolachlor through a rubber-packed column showed the greatest removal, with only 6 mg/L of the initial 400 mg/L remaining in solution. Removal efficiencies of steamexploded wood fibers were not improved by any of the methods investigated.
