  A hydride generation coupled to atomic absorption spectroscopy HGAAS method is presented for the determination of Selenium content in soil samples, alfalfa, animal feed, and water samples. The selenium distribution was studied in various locations in Zawia city. The studied areas were divided to seven different zones. The samples were digested in a mixture of mineral acid (HNO3, HCL, HCLO4 and H2O2). The Selenium element in acidified sample solution was reduced directly by treating it with Sodium borohydride (NaBH4), the metal hydride was introduced to the atomizer of AAS by inert carrier gas (N2, He). The instrument used for the generation of hydride was home built in the analytical lab and a batch method was implemented. The analytical parameters were optimized throughout the analytical procedure to give typical sensitivity (0.0055 pg/g). The Atomic Absorbance profile was recorded f.. Read More»
