Comparative Studies on the Sample Digestion Techniques of Alkali Fusion and Acid Dissolution in the Determination of Major Elements and Trace Elements in Stone;

Determination of trace arsenic(As) in peat by AFS after alkali fusion;

Simultaneous Determination of Chlorine and Sulfur in Plant by Ion Chromatography with Alkali Fusion;

74% by alkaline fusion of hydroxycaproic acid and its derivatives with sodium hydrate.

12-Phosphotungstic acid and cobalt are prepared with disused hard alloy anvil as starting materials,by means of alkali fusion treating,roasting,soaking,hydrolysis,crystallization to separate tungsten and cobalt.

I- was obtained from the kelp by alkali fusion, then oxidized by H2O2 in acidic solution, thus we can determine the iodine content by extraction spectrophotometry, which is about 426.

Celestite samples were decomposed by both acid digestion and alkali fusion techniques.

Corrosion failure analysis of caustic-fusion pan and research of preventive measures;

Through observation and analysis of a failed caustic-fusion pan of resorcinol equipment in a chemical factory,whilst various physical testing and chemical analysis of the failed pan and corrosion products were done.
