Abstract
The present work studies the removal of dissolved heavy metal example Copper ion (Cu+2) which represents a fetal effect on living organisms lives in synthetic wastewater by Mono Plus SP 112 cation exchange resin using pulsation technique considering some variables, this method was favored by its advantages, for example recovery of metal value, selectivity, less sludge volume produced and the meeting of strict discharge specifications also using synthetic resins is the method of choice for removing toxic metal contaminants in water and wastewater. Parameters studied: I. Initial Copper ion concentration (200, 300, 400 and 500 ppm). 2. Frequency (100, 150,200,250 and 300 rpm). 3. Amplitude (2, 2.8 and 3.6 cm). 4. Dose of resin per liter of solution (1, 1.5 and 2 g/I) 5. Layout of the disc (solid and two perforated) Conclusion: 2. The Copper ion removal efficiency decreases with increasing initial Copper IOn concentration. 2. As the frequency intensity increases the Copper ion removal is increased. 3. The highest Copper ion removal when the system is working at 2.8 cm amplitude. 4. Copper ion removal increases by increasing the dose of resin. 5. Solid disc gives the highest % removal up to frequency of 200 rpm after which the perforated disc (small perforation) overcome the solid disc. Copper ion removal by the ion exchange resin by vibrating technique was found to take place through diffusion controlled first order reaction. The mass transfer data were correlated by the following dimension less equation: Sh = 0.135 Se 0.33Re 0.7305 Isotherms also were studied and the experimental work shows that the data fit the Freundlich isotherm better than the Langmuir isotherm. Deviation of Sh calculated and experimentally= 0.207
