Study on Preparation and Dyeing Wastewater Adsorption Properties of Carbonized Cotton

摘要

Carbonized waste cotton were prepared by activate solution carbonization method. The effects of moisture content, carbonization time and carbonization temperature on the yield of carbonization were investigated. At the same time, the adsorption property of direct dye of the carbonized cotton products was studied. Results show that carbonization yield increased first and then decreased with the increasing of the moisture content using pure water as the activate solution at the same other conditions; Carbonization yield decreased as the extension of carbonization temperature and carbonization time. Carbonization yield and adsorption of direct dye increased when using phosphoric acid solution as the activate solution. Adsorption of direct dye increased with the increasing of phosphoric acid concentration.
