摘　　要：用胶体电荷滴定和Zeta电位测定法对漂白麦草浆 (BWAP)及过 1 0 5目的细小纤维(P1 0 5)的电荷密度和电荷特性进行了研究。并对硫酸铝和聚合氯化铝对漂白麦草浆的阳离子需求量及胶体滴定比率的作用进行了分析。结果表明 :pH值的改变对漂白麦草浆和P1 0 5的Zeta电位及胶体滴定比率 (CTR)影响很大 ,P1 0The Zeta potential measurement and colloid charge titration methods were used to analysis the charge density and the cationic demand of BWAP and P 105 .The results showed that the effects of pH on Zeta potential and CTR of both BWAP and P 105 were large,and P 105 had more cationic demand.The reactions of aluminum sulfate and polyaluminum chloride on cationic demand and CTR of BWAP were also discussed.
