INVESTIGATIONS OF THE EFFECTS OF ULTRASOUND ON SOME METAL AND NONMETAL SYSTEMS

The effects of power ultrasound on four metal-nonmetal powdered system s: copper-sulphur, iron-sulphur, zinc-sulphur and magnesium-sulphur in various solvents, such as hexane and carbon disulphide, are briefly e xamined here. For each system, a sonication time of 30 min was effecte d. The sonicated products are analysed by X-ray diffraction, X-ray flu orescence and atomic absorption spectrophotometry to determine their q ualitative and quantitative compositions and the percentage yields of the products obtained are then compared and discussed.
