Abstract. The removal ,of lincomycin, (LIN) from aqueous solution by birnessite was investigated by batch experiments. When the dosage of birnessite is 500 mg L −1 and the initial concentration of LIN is 15.5 μmol L −1, more than 90% of LIN was removed within 240 min at pH 4.90. Under different conditions, the reactions were well fitted with the ...
