Analysis of Chrome Tanned Leather Shavings Using Neutron Activation Analysis

Abstract

Chrome tanned leather shavings collected from the federal college of chemical and leather technology (CHELTECH) Zaria, Nigeria's tannery were analyzed using centre for energy research and training (CERT), Zaria Nigeria's miniature neutron source reactor (MNSR). The main aim of this work was to determine the concentration of chromium and other constituents of the shavings. Chromium is known for its human toxicity which includes skin irritation, lung cancer, as well as Kidney, liver and gastric damages. The disposal of this waste without treatment will constitute a serious impact on the environment. The result obtained indicates that Chromium is as much as 1%. The analyzed concentrations of As, Ba, Br, Co, Fe, La, Na, Sb, Sc, Sm and Zn in the sample are also presented. The results obtained were validated with the data obtained from the analysis of certified reference materials, IAEA-336 (Lichen) and IAEA 359 (Cabbage).
