REMOVAL OF URANIUM AND ASSOCIATED ELEMENTS FROM SINAI WELLS WATER USING THE DRIED AND CHEMICALLY MODIFIED ORANGE PEELS

It is well known that the natural cellulose has low ionic exchange properties, due to its characterization by a small number of carboxylic groups. Incorporation different functional groups can promote capacity. In this work, modification orange peel treating with sodium hydroxide and amination, phosphoration sulfonation. The ion exchanger been used increase capacity such materials, developing their swelling properties decreasing lignin content. A maximum uranium uptake 726 mg/g was observed at obtained optimum conditions using modified resin (ion No. VII). latter (0.841: 0.420) mm size peels were mixture sulfonic phosphoric acids. Ion VII as case study remove associated elements from Sinai wells water. main purpose work prepare resins Egyptian plant waste. Orange chosen because they are popular widespread wastes in Egypt.
