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.

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).

The removal of arsenic from solution has relied mostly on precipitation and adsorption processes and it has been considered that arsenic is the oxidation state that leads to the most effective removal by precipitation since the simple metal arsenates generally have lower solubility than the arsenites, and also arsenate is more strongly adsorbed on certain substrates, but this is pH dependent.
