Optimization of pH Value in Flotation Deinking

SHI Liang 1,ZHANG Su-feng 1,YANG Ya-ru 2,WANG Zhong-lin 2 (1.College of Papermaking Engineering,Shaanxi University of Science and Technology,Key Laboratory of Paper Technology and Specialty Paper Development of Shaanxi,Xi'an,Shaanxi Province,710021 China;2.Fujian Jiafeng Biological Chemical Co.,Ltd.,Sanming,Fujian Province,366000 China)  
pH value is an important environmental condition of enzyme catalysis reactions.This paper mainly studied the influence of pH value in enzyme deinking of flotation and in wastewater pollution load,it optimized the optimal pH value of enzyme was 8.64;through the analysis of pulp fibers' microscopic observation,the mechanism of enzyme deinking was discussed.
