一、方法要点用氯化银作载体,在同一张板上测定二氧化钛中铜、钒、钙、铝、铋、镍、铬、锡、铅、锰、砷、镁、铁、钴、锑15个杂质元素。本法对12种载体物质作了比较,氯化银对以上元素都有增强效应,能提高灵敏度一到二个数量级,达到1×10~(-3)%～1×10~(-4)%。相对均方差±5%～±15%。 First, the method points Silver chloride as a carrier, measured in the same plate of titanium dioxide in copper, vanadium, calcium, aluminum, bismuth, nickel, chromium, tin, lead, manganese, arsenic, magnesium, iron, cobalt, antimony 15 Impurity elements. The method of 12 kinds of carrier substances were compared, silver chloride on these elements have enhanced the effect can increase the sensitivity of one or two orders of magnitude, to 1 × 10 -3% to 1 × 10 -4, %. Relative mean square deviation ± 5% ~ ± 15%.
