摘要
分子筛的性能与生产它所用的氢氧化铝纯度有关。本法用等离子体光谱测定 Al(OH)_3中 Pb、Mn、Fe、Mg 等痕量杂质。样品用盐酸及过氧化氢分解。检出限达 0.1ppm;回收率在91—102%之间。
A method for determining by ICP-AES Pb,Mn,Fe and Mg in aluminium hy-
droxide for making molecular sieve has been developed.The samples were de-
composed with hydrochloric acid and hydrogen peroxide.All detection limits are
about 0.1 ppm.The average rates of recovery are between 91% and 102%.
