Abstract: The presence of heavy metals in water is one of the major environmental issues. In this study, desert date seed shells were employed as precursors for the production of activated carbon by chemical activation process using phosphoric acid (DDSSA) and potassium hydroxide (DDSSS). The activated carbon derived desert date seed were characterized using... Show More
