dc.description.abstractCellulose is the most abundant natural product; it has unlimited number of industrial applications. It reacts like alcohol and can be converted into various polymers with various functionalities. In this work cellulose extracted from Olive Industry Solid Waste (OISW) was converted to cellulose dialdehyde by oxidation with periodate, then reacted with the bifunctional amine 1,4-diaminobenzene to form cellulose diimine which then reduced to cellulose diamine by reacting it with sodium borohydride. The structure of the prepared polymers were analyzed by FT-IR, NMR (1H and 13C), and other spectroscopic and thermal methods. Produce cellulose diamine has a unique molecular structure, diamine compound holds the cellulose chain together and both form a kind of crown amine. The crown amine cages have several binding sites of nitrogen and oxygen that are distributed though the ring. These sites have high affinity for metals. The prepared cellulose diamine was used to extract toxic metals form wastewater. The metal that were extracted are lead, iron, and copper. The extraction efficiency of the cellulose diamine for these metals was evaluated as a function of pH, adsorbent dosage, temperature and time. The optimum conditions were the temperature was 30 oC, the time was about 120 min, pH was about 4.0 and the dosage is 0.5 g. Under these conditions a quantitative remove of metals from solutions concentrations 10, 20, 50 ppm was attained. The extraction efficiency for heavy metals were studied by using two type of polymer: powder and fiber polymer, we found powder polymer more efficient in extraction The kinetic calculations showed that, adsorption rate followed the Pseudo-second-order. The R2 for Pseudo-second-order equation was 0.9999.en_US
