Biosorbent for removal cationic pollutants and its making method

摘要

PURPOSE: A biosorbent for removal cationic pollutants and a manufacturing method thereof are provided to improve adsorption performance and affinity, and to remove basic dye effectively. CONSTITUTION: A manufacturing method of a biosorbent for removal cationic pollutants includes a step for substituting hydrogen of an amino group with one or more among an alkyl group, a cycloalkyl group or an aryl group, and a step for reacting aldehyde of 1ml~40ml and carboxylic acid of 1ml ~ 160ml in a mixing solution based on biomass of 1g. A substitution radical has the alkyl group, the cycloalkyl group, and the aryl group. The volume ratio of the aldehyde and carboxylic acid is 1~1/4.
