In recent years, polymeric adsorbent is gaining more interest over classical adsorbents such as clays and activated carbon due to its tunable physicochemical properties, structural diversity, reusability and selectivity. Therefore, the aim of this article is to summarize the available information on the adsorption studies of dyes using PVA and PVA-based polymer composite adsorbents. These materials were reviewed with emphasis on the experimental parameters (initial dye concentration, pH, adsorbent dosage etc.) and outcomes of the various adsorption studies were discussed. Furthermore, the isotherm models, kinetic and thermodynamic of the adsorption studies involved were also summarized. This review outlines the rationale for using the PVA-based composite adsorbents which have demonstrated good removal efficiency for several dyes. Future perspectives of the research work are also being suggested.

聚乙烯醇（PVA）和基于PVA的聚合物复合吸附剂吸附染料的研究进展

近年来，聚合物吸附剂因其可调节的物理化学性质，结构多样性，可重复使用性和选择性而比诸如粘土和活性炭之类的经典吸附剂引起了更多兴趣。因此，本文的目的是总结有关使用PVA和基于PVA的聚合物复合吸附剂对染料进行吸附研究的可用信息。审查了这些材料，重点是实验参数（初始染料浓度，pH，吸附剂用量等），并讨论了各种吸附研究的结果。此外，还总结了所涉及的吸附研究的等温模型，动力学和热力学。这篇综述概述了使用基于PVA的复合吸附剂的原理，这些吸附剂已显示出对几种染料的良好去除效率。
