Total Alkalinity (总碱度) Total Alkalinity (总碱度)Alkalinity refers to the amount and types of chemical compounds that can shift the pH toward the higher side of neutrality. Alkalinity is usually measured by the presence of bicarbonate (HCO3-) and carbonates (CO3=) and acts to buffer lakes from acidic inputs, thus is a measure…… http://www.samsco.com.cn/info/169419.htm
水中二氧化碳的来源及处理 水中二氧化碳的来源及处理SourceFree carbon dioxide (C02) exists in varying amounts in most natural water supplies. Most well waters will contain less than 50 ppm. Carbon Dioxide in water yields an acidic condition. Water (H2O) plus carbon dioxide (C02) yields carbonic acid (H2C03). The dissociation of carbonic a…… http://www.samsco.com.cn/info/367.htm
