Compared to wet season, arsenic is difficult to mobile in dry season. Attenuation constant in dry season is 0.3082(1/km), but it is 0.0569(1/km)in wet season. If initial concentration of As was 500μg/L without other contamination source in down stream, arsenic would deceased to 50μg/L in down stream 7.5km in dry season but 40km in down stream 40km. As is dominate species in river running throμgh mining area.

砷在枯水期较丰水期难以迁移，通过计算得到，在枯水期砷的衰减系数K值为0.3082(1/km)，而在丰水期为0.0569(1/km)；在污染口浓度达到500μg/L时，下游没有其它的砷的污染源(或会影响砷衰减的其它污染源)时，枯水期砷会在下游7.5km之后浓度降到50μg/L，而丰水期则要在下游40km之后才能降到同样的值，所以在丰水期砷污染的影响的流域更广。

The most common methods of removing arsenic from aqueous process streams are by precipitation as arsenic sulfide, calcium arsenate, or ferric arsenate, but it has been suitable for direct disposal to uncontained sites as they will produce leachate containing arsenic.

从水中去除砷是最常用的做法，工艺流程是通过沉淀类似硫化砷、砷酸钙或者砷酸铁，由于会产生含砷的沥出夜，因此这种方法适合用于不限制排放场所的直接处置。

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).

结果表明，外源砷浓度高时土壤砷形态以固定态砷为主，外源砷浓度低时以活性态砷为主，尤以交换态砷为主；施入紫云英土壤砷的活性增强；土壤AEC与活性砷含量呈线性正相关。

arsenic：砷

大家都晓得,砷(Arsenic)是五价元素,原子外层有五个价电子,如果一个砷原子代替了一个矽原子,那麼砷的四个原子便填上了原来矽四个价电子的位置,但砷的第五个电子无处置身,尴尬得很.
