soil using Cl as a tracer in a 5 mM solution of CaCl2. The AEC ranged from 0.01 to 1.86 cmolc kg 1 with an Many studies have shown that subsoils in the Piedmont region of average value of 0.68 cmolc kg 1. Retardation coeffithe southeastern USA have anion exchange capacity (AEC) and can adsorb anions such as nitrate (NO 3 ). Groundwater discharging to cients were determined from the BTC data and...

The transport properties of various anion and cation exchange membranes were studied in different electrolyte solutions using chronopotentiometry technique to get insight about the influence of the counter ion on the transport properties of the membranes. The investigated samples include heterogeneous ion exchange membranes varying in the functionality of fixed charged gro...

The parallel effects of the anion transport inhibitor DIDS (4,4'-diisothiocyanostilbene-2,2'-disulfonate) on net chloride flow and on chloride exchange suggest that a major portion of net chloride flow takes place through the anion exchange system. The "slippage" model postulates that the rate of net anion flow is determined by the movement of the unloaded anion transport site across the membra...

Zn-Al layered double hydroxide (LDH) nanoparticles with carbonate as the charge balancing anion in the interlayer space were synthesized using co-precipitation method. Then, the carbonate base Zn-Al LDH nanoparticles were doped with phosphate ion via anion-exchange reaction to synthesize Zn-Al-[PO43-]-[CO32-]. The structure and composition were characterized by X-ray diffraction (XRD), Fourier ...
