【摘要】 以粉碎后的717型强碱性阴离子交换树脂为骨架材料,采用甲醛与邻苯二酚聚合,制备了小颗粒氧化还原树脂。测定氧化还原树脂的交换容量为5.7 mmol/g;树脂的标准氧化还原电位为0.269v。将树脂应用于去除废水中的Cr(Ⅵ),效果良好。更多还原

【Abstract】 Small size redox resin was prepared on"717"strong-base anion-exchange resin and combined with the polymer of brenzcatechin and formalin. The redox capacity of such resin is 5.7 mmol/g, and it’s standard redox potential is 0.269 v.When it was used to remove Cr(Ⅵ) from the waste water, we got a good result.更多还原
