摘　　要：以高氯酸—磷酸混酸分解试样,氢氟酸除硅.硝酸溶液作介质.试液标液同倍稀释.柠檬酸—氰化锶溶液联合抑制磷酸根对钙的干扰.火焰成份和高度影响铬的测定准确度.The test portion is resolved in mixture of perchloric acid and phosphoric acid, silicon is removed with adding hydrofluoric acid. The test solution and standard solution are diluted by same times. It is restrained to influence of phosphoric acid with citric acid and strontium chloride solution. The composition and height of flame have influence on accuracy.
