single valence anion
相关语句
  一价阴离子
     The single valence anion (like Cl- and NO3-) had very small removal interference on Cr(VI). Only when the molar ratio of SO42-, PO43- and Cr(VI) in medium reached above 5:1 and 1:5, respectively, 2 kinds of inorganic anion could influence the adsorption of Schwertmannite on Cr(VI).
     一价阴离子(如Cl-和NO3-)对Cr(VI)的去除干扰极小,而仅当介质中SO42-和PO43-与Cr(VI)的摩尔比分别超过5:1和1:5时,2种无机阴离子才影响施氏矿物对Cr(VI)的吸附.

The test results of removing Cr(VI) in wastewater by adopting new type biocatalytic synthetic mineral Schwertmannite in the electro-plating wastewater of simulating many kinds of co-existed metal ions Cr(VI), Cu2+, Zn2+, and Cd2+ indicated that the Schwertmannite had very strong selective adsorption of Cr(VI) complex anion and the entire adsorption process accorded with langmiur equation. The best adsorption pH value was 6.0~7.0; the greatest adsorption amount was 55mg/g; when the initial Cr(VI) concentration was ≤100mg/L, the removal rate reached above 90%. At the test range of 20~50℃, the influence of temperature change on adsorption was very small. The single valence anion (like Cl- and NO3-) had very small removal interference on Cr(VI). Only when the molar ratio of SO42-, PO43- and Cr(VI) in medium reached above 5:1 and 1:5, respectively, 2 kinds of inorganic anion could influence the adsorption of Schwertmannite on Cr(VI).

在模拟多种金属离子[Cr(VI),Cu2+,Zn2+和Cd2+]共存的电镀废水中,采用新型生物催化合成矿物无定型羟基硫酸高铁(Schwertmannite,施氏矿物)去除废水中的Cr(VI).实验结果表明,施氏矿物对Cr(VI)络阴离子具有很强的选择性吸附,整个吸附过程符合Langmiur方程.吸附的最佳pH值为6.0~7.0,最大吸附量为55mg/g,且当Cr(VI)初始浓度≤100mg/L时,去除率达90%以上.在温度20~50℃范围内,温度变化对吸附的影响较小.一价阴离子(如Cl-和NO3-)对Cr(VI)的去除干扰极小,而仅当介质中SO42-和PO43-与Cr(VI)的摩尔比分别超过5:1和1:5时,2种无机阴离子才影响施氏矿物对Cr(VI)的吸附.
