The results showed that the curve of streaming potential indicated sharply the endpointoftitration for cationic starch.
结果表明流动电位曲线敏锐地指示了低电荷密度的阳离子淀粉胶体滴定的终点。

The endpointoftitration is controlled by instantaneous titration controller and titre is measured by Mariotte constant current titrator and timer.
瞬时滴定控制器可准确地控制滴定终点,使分析结果准确可靠。

The procedure doesn't use indicator and the precipitate doesn't to separate. The endpointoftitration is obvious. The operation is simple , fast , accuracy and good repetition.
