The ground water ammonium sorption onto Croatian and Serbian clinoptilolite.
The removal of ammonium from the Valpovo region ground water (VGW) with the use of natural clinoptilolite samples from the Donje Jesenje deposit (Croatia) and the Zlatokop deposit in Vranjska Banja (Serbia) was studied. The natural Serbian (SZ) and Croatian zeolites (CZ) were transformed to the Na-form (Na-CZ and Na-SZ) in order to increase the exchange capacity of zeolite. The CZ and SZ theore...
متن کاملEffect of dissolved organic matter on ammonium sorption kinetics and equilibrium to Chinese clinoptilolite.
In the in-situ remediation of ammonium (NH4+) in groundwater by a sequential reactive barrier filled with zeolite, it is of great importance to understand the mechanisms of NH4+ sorption to zeolite. In this study, the effect of dissolved natural organic matter on NH4+ sorption to natural Chinese clinoptilolite was studied by batch experiments taking humic acid (HA) as a model substance. The sur...
متن کاملSORPTION KINETICS OF SELECTED HEAVY METALS ADSORPTION TO NATURAL AND Fe(III) MODIFIED ZEOLITE TUFF CONTAINING CLINOPTILOLITE MINERAL
In the research described in this paper, studied was sorption capacity of natural and ferric modification of zeolite tuff containing mineral clinoptilolite from the Nižný Hrabovec deposit to remove potentially toxic metals (ionic forms of chromium, nickel, copper and aluminium) from their water solutions. We reported that the Fe (III) zeolite has an enhanced ability to sorption of Cu (II), and ...
متن کاملSTUDY ON SORPTION OF SOME TOXIC AND HEAVY IONS IN DILUTE SOLUTIONS BY CLINOPTILOLITE
The deposits of clinoptilolite (CLI) in Iran after activation with sodium chloride or sodium hydroxide solution was subjected to ion exchange with some heavy and toxic cations. The results showed that the absorption for Ca2+ (7.5 ppm), Cu2+ (50 ppm), Zn2+ (40 ppm), Cd2+ (40 ppm), Pb2+ (500 ppm) and Al3+ (5 ppm) were 95.2, 96.70, 93.30,99.12, 99.2 and 90.0 percents, respectively. The noteworth...
متن کاملammonium sorption rate by some soils series of golestan province
sorption reactions in many heterogeneous systems are important. adsorption is a time dependent process and knowing the adsorption rate is essential for designing, evaluating and recovering the adsorbents. at the present study, an ammonium adsorption kinetic experiment by some soils series of golestan provice, which is varying in mineralogical and textural properties was conducted using solution...
