| 摘 要： | 文章对不同改性软锰矿处理模拟染料废水进行了研究。改性后软锰矿能有效提高对模拟染料废水的脱色率和对pH的适应能力,同时能降低软锰矿的用量。在双氧水与软锰矿协同作用下,脱色率从14.35%提升到92.68%。对天然软锰矿和改性软锰矿进行分析显示,改性后的软锰矿颗粒粒径小,大小分布均匀,具有比天然软锰矿更好的孔道结构和表面羟基化程度。

| Abstract: | Disposal of wastewater simulated by active red B-3BF with modified pyrolusite was studied.Modified pyrolusite has better effect of decolorization and better adaptability of pH as well as lower consumption of pyrolusite amount.When cooperated with H2O2,removal of chroma can be improved from 14.35% to 92.68%.Analysis of natural and modified pyrolusite showed the modified pyrolusite granularity was smaller and more equal than natural pyrolusite while holes and hydroxyl extant were better either. |
