| Abstract: | A sensitive method for determination of tin in tropical fruits by hydride generation-atom ic fluorescence spectrometry was proposed.Determination condition was chosen through orthogonal ex periment.Parameters affecting the sensitivity in determination of tin were studied and opti mized by using the data from SAS treatment of the experimental results.Detection limit was0.004mg /kg.Correlation coefficient was0.9999.Recovery rate was89.6%~106.6%.The relative error was0.5%~0.8%. |
