聚乙烯吡咯烷酮与各类染料的缔合作用比较

Comparative Study on Associative Ability of Polyvinyl Pyrrolidone (PVP) with Dyes

用紫外可见吸收光谱法研究了阴离子染料、阳离子染料和非离子染料等各类染料与聚乙烯吡咯烷酮缔合作用的差异,以及染液pH对缔合作用的影响。

The associative abilities of PVP with various classes of dyes such as anionic, cationic, and non-ionic etc. are investigated by using UV-VIS and then a comparative study is carried out, along with the effect of bath pH on the association.
