The study is aimed at assessing how the date palm wood fibers (DPWF) can be used for the removal of heavy metals from water. The study involved examination of the radical polymerization and graft polymerization parameters such as reaction period, reaction time, monomer volume, amount of the catalyst, and concentration of initiator to obtain the maximum yield of graft polymerization. Fiber and copolymer were characterized using SEM and FT-IR spectroscopy to ensure the completion of polymerization. Hydroxylamine hydrochloride was used for treating the grafted copolymers for the preparation of polyamidoxime chelating resin, which was then examined for removing the heavy metal ions. Different resin dosages, contact time, and initial concentrations were used, and the batch technique experiment was utilized. The study also applied the Langmuir and Freundlich isotherm model, and Langmuir was found to be better. The absorption ability was found to be better for polyamidoxime resin for metal ions of cadmium (II), chromium (III), and lead (II).

通过使用H2O2 / Fe ++作为引发剂将丙烯腈接枝共聚到椰棕纤维上，从水中除去镉（II），铬（III）和铅（II）重金属离子

该研究旨在评估枣椰子木纤维（DPWF）如何用于从水中去除重金属。该研究涉及自由基聚合和接枝聚合参数的检查，例如反应时间，反应时间，单体体积，催化剂的量和引发剂的浓度，以获得接枝聚合的最大收率。使用SEM和FT-IR光谱对纤维和共聚物进行表征，以确保聚合完成。盐酸羟胺用于处理接枝共聚物，以制备聚酰胺型肟螯合树脂，然后检查其是否去除了重金属离子。使用不同的树脂用量，接触时间和初始浓度，并利用间歇技术实验。该研究还应用了Langmuir和Freundlich等温线模型，发现Langmuir更好。发现聚poly肟树脂对镉（II），铬（III）和铅（II）的金属离子的吸收能力更好。
