摘要：

The removal of nickel ions from aqueous solutions, using fly ash, a cheap industrial by-product, was investigated. Its addition to the solution raised the pH, effectively removing the totality of the nickel ions. The removal may be attributed, depending upon the dispersion pH, partly to adsorption but mainly to precipitation. The fly ash performance was compared to that of other adsorptive materials (activated carbon and a synthetic zeolite). The synthetic zeolite was more efficient in removing the nickel ions, especially at low pH values, but is evidently a more costly material.
