EVALUATION OF MICROWAVE-ASSISTED EXTRACTION FOR ORGANOTIN DETERMINATION IN VEGETAL AND SOIL MATRICES

A new method for the extraction of methyl-, butyl-, phenyl- and octyltin compounds from soil and vegetal samples was proposed. The extraction procedure is based on an acidic solution in methanol for both matrices using a microwave system. The optimal conditions for each matrix were determined using...
