Abstract
Environmental pollution with heavy metals is a serious issue worldwide posing threats to humans, animals and plants and to the stability of overall ecosystem. Chromium (Cr) is one of most hazardous heavy metals with a high carcinogenic and recalcitrant nature. Removal of Chromium ions from synthetic tannery wastewater was investigated by using different Adsorbents like Activated Carbon, Bentonite, coffee Powder and Moringa powder with various Parameters including contact time and adsorbent dosage. Activated carbon Adsorbent was the Effective and removal efficiency reached about 98% at contact time 120 minute. The result Shows that Activated Carbon, Bentonite, coffee Powder and Moringa powder can be used as good adsorbents for the removal of Cr ions from synthetic tannery wastewater.
