Assessment of Some Selected Metals from Textile Effluents in Amhara Region Using AAS and ICPOES

Abstract

Article History Keywords Heavy metal Textile wastewater AAS and ICP-OES. Heavy metals are some of the common pollutants that are found in industrial wastewaters a variety sources one of them textile industries. In Ethiopia, there are more than fourteen major textile and garment factories. The study of industrial wastewater, it is important to select the appropriate wastewater treatment program. Samples of textile effluents from textile industries found in Amhara Regional State Bahir Dar, Kombolcha, and Debre Brihan textile industries were collected. Heavy metal concentrations effluents were determined using FAAS and ICP-OES. The determined heavy metal concentration of Pd 0.85 to 0.61, As 1.3 to 0.4, Cr 0.08 to 0.03, Zn 2.6 to 0.32 and Mn 0.37 to 0.25 mg/L by FAAS. The determined heavy metals in all textile industries didn't have significant effluence to environment, but there is a significant difference between FAAS and ICP-OES. The concentration of all the studied heavy metals except Mn were comparable with the WHO and EEPA guideline. This study suggests quick intervention and closes monitoring to arrest and solve the growing environmental pollution. Contribution/Originality: The paper's primary contribution is finding that influence of environmental pollution assessment with standards of EEPA and WHO and determined heavy metals Pb, As, Cr, Zn and Mn from textile industries waste water effluents in Ahmara region, Ethiopia and comparison of FAAS and ICP-OS methods.
