본발명은지질을탄소나노튜브에결합시킨후 지질의환원력을이용해금속나노입자를탄소나노튜브에고정화는탄소나노튜브의제조방법에관한것이다. 본발명에의한방법은탄소나노튜브에결합된지질의환원력을이용하여금속을탄소나노튜브표면에서환원시켜나노입자형태로고정시킬수 있다. 본발명은탄소나노튜브에결합되는지질을통해금속나노입자의생성이나크기도제어할수 있다. 본발명의방법은자연계에널리존재하는지질을이용하므로친환경적으로금속나노입자를탄소나노튜브에고정시킬수 있다.
Abstract:
PURPOSE: A method for producing a biosorbent is provided to effectively remove basic dye in broad pH concentration range and enhance affinity. CONSTITUTION: A biosorbent for removing cationic pollutant comprises a compound containing one or more from carboxylic group, sulfonic acid or phosphate group which is additionally bound to a biomass. The carboxylic group bound to the biomass is denoted by the chemical formula 1.
Abstract:
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.
