| Abstract: | In the presence of cetylpyridine bromide, tin can form an orange ternary complex with phenylfluone in 0.3mol/L sulphuric acid medium. The maximum absorption of the complex is at 510 nm and molar absorptivity, 1.07105. Beer's law is obeyed in the range of 08g/50ml for Sn. The standard deviation of sample is less than 0.03%. The method has been used for determination of multiple metal ores with satisfactory results. |
