砷酸钙

以砷酸钙为基料的杀虫剂或制品

Insecticidal preparation or articles based on calcium arsenate

CO2主要影响3∶2和5∶3的砷酸钙盐，而对4∶2砷酸钙盐的影响较小。

The effects of CO_2 mainly occur on the 3 ∶ 2 and 5 ∶ 3 calcium arsenates , and less on the 4 ∶ 2 calcium arsenate .

CO2分压越大，砷酸钙盐发生不一致溶解的酸度越低；

The higher the CO_2 pressure is , the lower the acidity of the incongruent dissolution is .

这对不同类型砷酸钙盐废物的处置是否应考虑CO2的因素提供了依据。

These conclusions can give some suggestions whether the CO_2 effects should be considered in calcium arsenates wastes disposal .

单一的碳酸钙或氧化钙在高温下与砷化物作用，生成难分解的砷酸钙，加入少量这些物质，其固砷率分别可达73.0%、47.4%。

Single calcium carbonate or single calcium oxide reacts with arsenic compounds under high temperature and generates calcium arsenic which is hard to discompose . By adding a small amount of these substances , their arsenic-capturing rates are up to 73.0 % and 47.4 % respectively .
