Three methods were used to pre-treat the soil slope to be measured, including digestion by emblem wave, digestion by sealed container and digestion by electric heating plate, and then determine the pot, zinc, lead, fu, nickel and chromium by atomic absorption spectrophotometry. The results show that: Huibo digestion can completely digest soil slope samples, and it is simple and fast, which is superior to the other two methods.
