用化学方法进行灰土混合料中石灰含量的测定需比较土、石灰和灰土混合料中钙离子的含量。这些方法依据的原理是土、石灰及灰土混合料中的钙化物被盐酸浸提时会转化为可溶性氯化钙。将钙离子从其它干扰离子中分离出来后,再用重量法或体积法计算
Determination of lime content in lime-soil mixes by chemical method The contents of calcium ions in soil, lime and lime-soil mixes need to be compared. These methods are based on the principle that calcium compounds in soil, lime and lime-soil mixes are converted to soluble calcium chloride when leached with hydrochloric acid. Calcium ions from other interfering ions isolated, and then gravimetric or volumetric method
