摘要
Abstract
It studied a method of microwave digestion-GFAAS for the determination of total lead in soil. HNO3 and HF were added into the soil samples,the microwave digestion under the certain condition was conducted and in a constant temperature heater to drive acid and remove silicon, then total lead content in soil was determined by Graphite Furnace Atomic Absorption Spectrometric(GFAAS) method. Compared with the national standard (GB/T 17141-1997) digestion method ,and determined the different soil and soil standard substances, the results show that: the two methods have no significant difference. This method is well repeatable, with less reagent dosage, safe and easy to control and it is reliable.关键词
