Resum
A natural clinoptilolite in its potassium form (KNC) was modified by impregnation of hydrated metal oxides (HMO) of aluminium (III) (KAlC), iron (III) (KFeC) and manganese (IV) (KMnC) for the simultaneous ammonium and phosphate recovery from urban wastewaters. The resulting pHpzc of the HMOs on the modified zeolites (7.3 ± 0.3 for KAlC, 6.4 ± 0.4 for KFeC and 6.9 ± 0.3 for KMnC) are suitable for phosphate sorption at pH of treated urban wastewaters (6–8). The sorption capacity for phosphate...
