Chromium III in Gezira Tannery Corporation Wastewater (Wad Medani, Sudan)
Ammar MS Abdalla, Nabil HH Bashir and Yousif OH Assad
This study was initiated to investigate the level of chromium III in Gezira Tannery Wastewater and compared with the permissible limit stander for chromium III. Samples of Gezira Tannery Corporation (GTC) wastewater (WW) were collected from both the mouth and the tail of the drainage stream. These samples were analyzed to determine the concentrations of Cr using atomic absorption spectrometric (AAS) method. Results of AAS method showed high quantities of Cr III (1.85%), i.e. above the permissible limit (0.0001%).
