| Abstract | ||||
| In the current study the free floating macrophyte Pistia stratiotes L. belonging to family (Araceae) powder was used as bioadsorbent material for immobilization of Cadmium from contaminated water samples. Design experiment was employed to reduce the number of trials and examine the effect of different controlling parameters at the same time on cadmium adsorption process. From the results we observed that the size of powdered materials were ranged from 116.6 -187.5 nanometers. The maximum removal percent (92 %) was recorded at pH 8, 190 min. of contact time, 28.75 mg/l of Cadmium concentration and 3.875 g of adsorbent material. Key wards: Pistia stratiotes, Cadmium, bioadsorbent, pollution, Experimental design. Introduction Aquatic pollution caused by heavy metal represents an important environmental problem worldwide due to its toxic effects (Shreadah et al. 2006; Said et al. 2006; Khalil et al., 2013; Younis et al., 2014a.Nafea and Zyada. 2015, Nafea.2016, Nafea,2019a.Nafea.2019b). Heavy metals are widely used in industrial sectors such as mining, fertilizers, medicine and agriculture | ||||
