The ferrous oxalate with crystal water was prepared with ferrousammoniumsulfate and oxalic acid in acid medium.
采用硫酸亚铁铵和草酸溶液在酸性介质条件下合成含有结晶水的草酸亚铁。
2
There were no apparent different effects between using ferroussulfate and using ferrousammoniumsulfate, the former was much cheaper and no secondary pollution.
用硫酸亚铁的效果与用硫酸亚铁胺的效果相差不大，且前者价格便宜，使用中不会造成二次污染；
3
In accordance with ferrousammoniumsulfate in water samples to calculate the amount of material to restore the volume of oxygen consumption, which was potassium dichromate titration reflux.
