[Determination of Pb in flying coal-ash by GTAAS].
Biochemical was chosen as the stability and improvement reagent to make insoluable solid into slurry, which could be sampled directly to determine Ph in flying coal-ash, one of the environmental samples. The optimal conditions of Hitichi GTAAS 180-80 were decided by experiments, such as linear range 7.0-66.7ng/mL atomization temperature 2000 degrees C and amount of biochemical 0.2-1.2 per thousand. The effects of acid, stirring and particle concentration were also addressed.
