文中论述了四种检测部分水解聚丙烯酰胺浓度的方法。其中淀粉—cdl_2法最适于各种条件下的痕量组分的检测;浊度法在很宽范围和条件下,可获得很好的线性关系;紫外光法要求较纯的水质才能获得准确的测定结果,但简捷;粘度法不宜用于检测HPAM的波度。
In this paper, four methods for detecting the concentration of partially hydrolyzed polyacrylamide are discussed. The starch-Cdl_2 method is most suitable for the detection of trace components under various conditions; the turbidity method can obtain a good linear relationship under a wide range and conditions; the ultraviolet method requires more pure water quality to obtain accurate The determination results, but simple; viscosity method should not be used to detect the HPAM wave.
