Abstract

Swelling of synthesized N-vinylpyrrolidone-based polymer sorbents in aqueous solutions with different pH has been studied. The initial rate and degree of swelling, their dependence on the ratio of functional monomer and cross-linking agents in the polymer samples synthesized in various solvents have been found. It has been shown that the sorption of nitrophenols depends on the swelling of the polymers and increases with increasing amount of a cross-linking agent, but is not directly related to the specific surface of the sorbent.

N-乙烯基吡咯烷酮基聚合物溶胀对硝基酚吸附的影响

摘要

研究了合成的基于N-乙烯基吡咯烷酮的聚合物吸附剂在不同pH值下的溶胀。已经发现了在各种溶剂中合成的聚合物样品中的初始速率和溶胀度，它们对功能性单体和交联剂的比例的依赖性。已经表明，硝基酚的吸附取决于聚合物的溶胀并且随着交联剂的量的增加而增加，但是与吸附剂的比表面没有直接关系。
