    Abstract: This study offers an integrated process for treatment and recycling of tannery waste, it has a dual purpose. First the activated carbon (AC) has been prepared from leather shaving (LS) and goat hair (GH) by physical activation. Both the raw material and the prepared activated carbon were analyzed by DTG, TGA, and SEM. The adsorption tests of methyl... Show More

    Abstract: The gamma ray spectrum obtained from a 3.7 × 104 Bq 252Cf source after passing through different shielding materials at different thicknesses and different arrangements were detected with a NaI(Tl) detector was fed to a computerized MCA to have a spectrum. This was then stored and subsequently unfolded. The unfolded dose spectra of the fission gamm... Show More
