METHOD 900DETERMINATION OF WATER IN WASTE MATERIAL
简介:2.1 A sample of the material to be tested is treated with a specially formulated calcium
hydride reagent which reacts with water in the sample to liberate hydrogen gas as shown below:
CaH2 + 2H20 6 Ca(OH)2 + 2H2 8
2.2简介:2.1 A sample of the material to be tested is treated with a specially formulated calcium
hydride reagent which reacts with water in the sample to liberate hydrogen gas as shown below:
CaH2 + 2H20 6 Ca(OH)2 + 2H2 8
2.2 The reaction is carried out in a sealed pressure vessel and the resulting pressure is
then measured using a specially designed meter. The results are displayed directly in weight or
volume percent, depending on the sampling method used.
2.3 The reaction is quantitative, measuring all water present in the sample over the range详细>
