摘要
用TOA-IBK系统萃取,火焰原子吸收光谱法在同一条件下测定土壤、蔬菜中的铅镉。考察了TOA、KI、盐酸、抗坏血酸用量、萃取时间、放置时间及在同等实验条件下钙、镁、铁等金属离子和酸的用量的干扰影响情况。
Then at the same condition, determine the lead cadmium content of the soil and and vegetable samples by flame ion spectrum method. Observe the extraction time the laying time the dose of TOA .KI. Hydrochloric acid and ascorbic acid. After this, inspect the influence of acid dose and the change of the metal ion （calcium. magnesium, iron etc.） underthe same experimental circumstance.
