The removal of arsenic from arsenic-bearing waste water is the urgent problem in hydrometallurgical processing of nonferrous metals. Precipitation of arsenic as its environmtal friendly precipitate, scorodite from ferrous sulphate solutions is of great interesting. The influence of temperature on crystalline、specific surface area, particle size and purity of arsenic precipitates were researched in hydrothermal precipitation process.The results showed that when temperature lower than 160℃，there are no scorodite formed but other ferric arsenate. An increase in temperature and initial pH produced precipitates with smaller particles、larger specific surface area, better crystalline and high purity.
