calcium bicarbonate

1. Ammonium sulphate with calcium carbonate as gross by-product could be obtained from the raw materials including phosphogypsum, ammonium bicarbonate and ammonia water.
   以磷石膏、碳酸氢铵和氨水为原料制备硫酸铵，并用盐酸处理碳酸钙粗品制备氯化钙。
2. It was found by in-situ monitoring that the Xiangshui River has a very low concentration of calcium and bicarbonate, which does not match with the huge tufa deposits in the riverbed and the dense vegetation cover in surrounding area.
   文章报道了响水河河水的现场监测结果，得到响水河河水的Ca2+和HCO-3非常低，这明显与河床中大规模钙华的存在和景区内发育的茂密植被不匹配；
3. The organic in cooling water was oxidated by ozone and carbon dioxide was produced. With the increasing of concentration of carbon dioxide in water, calcium carbonate could turn into calcium bicarbonate and concentration of ca2+ in water increased.
   臭氧可以氧化循环冷却水中的有机物，生成二氧化碳，水溶液中二氧化碳浓度的增加，可使碳酸钙转化为碳酸氢钙，这样就使冷却水中Ca2+浓度增加。
