【Abstract】 Among the various methods for preparing coa ted graphite tubes studied, the supersonic soaking technique has been found to be the best. The time needed for coating is greatly shortened and both the sensitivity and precison are considerably improved. Good results were abtained for the determination of tin in aluminium alloys using such coated tubes.更多还原
