摘要：

The metal binding properties of the agricultural waste obtained from apple juice processing and cider production were enhanced by chemical modification This residual lignocellulosic biomass contains acidic groups with cation exchange properties. Solutions containing mixtures of copper, zinc and nickel ions were percolated through packed beds. The apple residues showed higher selectivity for copper ions and the exchange capacity increased with decreasing concentration of the solutions. The sorbed ions can be easily stripped from the apple waste with hydrochloric acid with no loss of binding efficiency over several binding-stripping cycles.
