| Abstract: | A method of determining trace lead in silver containing tin solder sample with flame atomic absorption spectrum was worked out. In the procedure of the method, thiourea was used to form complex silver ion for eliminating the interference of silver and tin to lead determination according to the relatively lower boiling point of quadrivalence tin chloride and tin volatilization. The method is proved to be accurate, reliable, convenient and quick, absolutely suitable for the assaying of trace lead in silver tin solder. |
