    Abstract
    Water Remediation from Heavy Metal Ions by non modified and ZnCl2 modified coffee husk: Batch and Fixed- Bed Column Study Chromium is considered a key strategic metal having wide ranging applications in various industries 1. The carcinogenic properties of chromium associated with itsoxidation states, and its immense consumption has been a focus of research 2. Cr(III) is considered as an essential trace mineral, plays a key role in mammalian metabolism and reduction of blood glucose levels 1. Cr(III) is also a stable oxidation state of chromium, whereas Cr(VI) is a strong oxidizing agent and its exposure causes health hazards 1, 2. Although disagreements exist about its permissible range in drinking water, however according to US Environmental Protection Agency (EPA) and World Health Organization (WHO), the permissible range equals 0.05μg mL−1 and 0.1μg mL− 1, respectively 3. In recent years, several strategies involving the use of low cost solid phase extractor essential to addresses such problems .The performance of coffee husk for lead removal was studied in a previous study 4 Thus, the current study will be discussing the retention of Cr(VI) by the modified CH. Thus, the current demonstration focuses on: i) developing a simple, rapid, highly selective, and eco friendly SPE such as modified CH for preconcentration of trace and ultra trace concentrations of Cr(VI) in water samples; ii) assigning the crucial role and mechanism of the retention of Cr(VI) and finally iii) developing CH packed column for complete retention of Cr(VI).
