摘要：
A highly selective and sensitive method has been developed for the determination of arsenic in fly ash and sulphide ore by flame atomic absorption spectrometer using hydride generator (FAASHG). A number of samples have been analyzed using the proposed method. The fly ash sample was received from National Council for Cement and Building Materials (NCCBM) and the sulphide ore sample was received from Hindustan Zinc Ltd., India. The validity of the method has been established by comparing the results obtained from two certified reference materials of NIST 1633(b) and CRM COD 161a of MBH. The standard deviation has been calculated for each measurement.
