报道了以水为溶剂,以四甲基碘化铵为支持电解质,用导数示波极谱法直接测定聚丙烯酰胺产品中微量的残余丙烯胺单体。本法不仅适用于粉状聚丙烯酰胺产品,也适用于胶状聚丙烯酰胺产品中的残余丙烯酰胺的测定。由于本法不需从聚丙烯酰胺产品中分离残余丙烯酰胺单体,故操作简便、快速。经过一年多的聚丙烯酰胺样品例行测定,实际证明本法是切实可行的。 Reported the use of water as a solvent, tetramethylammonium iodide as a supporting electrolyte, direct determination of traces of polarographic polyacrylamide traces of residual acrylamide monomer. This Law applies not only to powdery polyacrylamide products but also to the determination of residual acrylamide in gelatinous polyacrylamide products. Since this method does not require the separation of residual acrylamide monomer from the polyacrylamide product, it is easy to handle and fast. After more than a year of polyacrylamide samples routine determination, the actual proof of this Act is feasible.
