查询词典 arsenate

There are other metal arsenates, such as those of Fe,Zn,Cu, and Pb, which are less soluble and more stable in the neutral pH region than calcium arsenates or ferric arsenate, but these have not been seriously considered as disposal forms.

还有其他金属砷酸盐，例如那些 Fe、 Zn、 Cu和 Pb，比起砷酸钙或者砷酸铁来，这些物质在中性的 pH 值范围内很少是可溶并且更稳定的，但是这些物质没被以处理的形式认真慎重地考虑过。

When pH is 10, adsorption time is 30 min, dosage of bone char is 0.6 g/L, the original concentration of As in drinking water is 0.5 mg/L, As removal can reach 95.2%. The adsorption behavior is fitted both with Langmuir and Freundlich isotherm. The adsorption mechanism is supposed to be Ca—OH functional groups combined with anion. And there may occur the co-precipitation between calcium hydrogen arsenate and hydroxylapatite in the aqueous solution, and ions also exchange. The saturation adsorption capacity of As reaches 4.688 mg/g. Indexes of effluent are in good agreement with the WHO stringent drinking water standards (0.01 mg/L).

研究结果表明：在pH=10，吸附时间为30 min和骨炭加入量为0.6 g/L，饮用水砷初始质量浓度为0.5 mg/L时其砷去除率可达95.2%；骨炭吸附砷的行为同时符合Langmuir和Freundlich等温吸附模型；其吸附机理可能是Ca—OH官能团结合HASO4阴离子，并产生砷酸氢钙和羟基磷灰石的共沉淀，另外还存在离子交换作用；吸附柱的饱和吸附容量为4.688 mg/g；出水砷浓度符合世界卫生组织规定饮水砷标准(0.01 mg/L)。

It was discovered that this modified kaolin had ideal capability of removing arsenic from water because of its giant active surface and coordinate action, intensify, for arsenate ions AsO(superscript 3- subscript 4 and Fe(superscript 3+) fixed on the framework, and achieving the aim of removing the minimal content of arsenic from the water.

以高岭土为原料通过碱熔合成得到类似于分子筛的笼状骨架结构，并将Fe(上标 3+)通过离子交换吸附，负载在其骨架上，实现改性；利用改性后的吸附剂具有大的活性表面积，以及砷阴离子AsO(上标 3-下标 4与Fe(上标 3+)的强配位能力，实现了基于配体交换的固液分离的从微量含砷水中去除砷。
