Removal of mercury from aqueous solutions by nitrogen-containing chemically modified cotton
A study was made of the effectiveness of four different chemically modified cotton celluloses, cotton impregnated with cross-linked polyethylenimine (CPEI), O-(2- diethylamino)ethyl (DEAE) cotton, O-(2- aminoethyl) (AE) cotton, and cotton impregnated with polyethylenimine (PEI), for the removal of m...

| Summary: | A study was made of the effectiveness of four different chemically modified cotton celluloses, cotton impregnated with cross-linked polyethylenimine (CPEI), O-(2- diethylamino)ethyl (DEAE) cotton, O-(2- aminoethyl) (AE) cotton, and cotton impregnated with polyethylenimine (PEI), for the removal of mercury from aqueous solutions. At equal weights of the celluloses, effectiveness was found to be proportional to the amine content, therefore, in descending order of effectiveness are CPEI cellulose, AE cellulose, PEI cellulose and DEAE cellulose. The sorbed mercury can be readily recovered from the celluloses, which can then be re-used. |
