Abstract
The adsorption behaviour of 4 vinyl pyridin grafted poly (ethylene terephthalate) fibers was studied towards the copper (II) ions in aqueous solutions by a batch equilibriation technique. The influence of treatment time, temperature, pH of solution, metal ion concentration and percent graft yield on adsorbed amount were investigated. One and half an hour of adsorption time was found sufficient to reach adsorption equilibrium for copper(ll) ions. It was found that the adsorption isotherm of Cu(II) ions fits to Langmuir type isotherms. The highest adsorption capacity was found to be 0.973 m m o I copper(ll) ion per gram adsorbant. The heat of adsorption value was calculated as -9.57 kj $mol^1$. It was found that the reactive fibers are stable and regenerable by acid treatment without losing its activity.
