Abstract
PURPOSE: A dye adsorbent that is made by coagulating powdery activated carbon and powdery cellulose with deacetylated and insolubilized chitin, thus having large adsorption power and high adsorption rate for dyes and being free from carbon leak.
CONSTITUTION: An acidic slurry is made by mixing (A) 10W70wt% of powdery activated carbon, (B) 5W30wt% of powdery cellulose of 100micron or less number- average fiber length and (C) deacetylated chitin so that the sum of (A) and (B) becomes 75wt% or less. An alkali is added to the mixture so that the pH is adjusted to over 8 to insolubilize the deacetylated chitin and disperse the activated carbon uniformly in the forms where most parts of the carbon are captured on the surface and gaps or cavities that are formed by fiber entanglement and the rest part of the carbon in free form is made into secondary coagulation particles, resulting in coagulating the powdery activated carbon and powder cellulose with insolubilized deacetylated chitin.
