电位法测试PTA含量

Determination PTA content with potentiometry

用过量的、一定浓度的氢氧化钠溶液与乙二醇/对苯二甲酸浆料中的对苯二甲酸反应,在电位滴定仪上,用盐 酸标准溶液滴定剩余的NaOH溶液。根据消耗的盐酸标准溶液的体积,计算出EG/PTA浆料中PTA的含量。

Use the surfeit of, finite concentratain sodium hydroxide solution , with EG/PTA the reaction of PTA that syrup anticipate the inside. By potentiometric titration the aqua of sodium hydroxide solution with hydrochloric acid standard solution. Compute the EG/ the PTA syrup anticipates the inside PTA contains the deal.
