    Improvement of the stability for determination of low lead content in TSP by FAAS
    (2010) Xiong Xiao-hong
    The instrument parameters are optimized for determination of lead content of less than 50μg/g in TSP by FAAS,including the analysis line,lamp current,slit width,combustion height,acetylene flow,V(C_2H_2)/V(Air).After the optimization,the standard deviation of lead determination is less than 4 mg/kg,both the stability and accuracy of determination are improved.
