【摘要】 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—cdl₂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。更多还原

【Abstract】 Four methods for measuring the partially hydrolyzed polyacrylamideconcentration are discussed in this paper. Among these, the Starch-Tri-iodide method is most suitable for the measurement of trace componentunder various conditions. The Turbidimetric method can give a good linearrelationship over a wide range and condition. Ultraviolet spectroscopy canobtain accurate measurement results only on the condition of more pure wa-ter quality, but this method is simple and direct. the viscosity method isnot suitable for the determination of HPAM concentration.更多还原
