Field measurements included pH, Eh, EC, temperature, depth of water table and depth of sample collection. Separate, field preserved sub-samples were collected for cation (ICP-MS/OES), anion (IC), alkalinity (titration), DOC, P04 and Au and PGE analysis (using carbon sorption).

Pretreatment is often used to reduce fouling. Methods include heating, pH adjustment, chlorination, activated-carbon sorption, or chemical precipitation. Other factors such as membrane pore-size distribution, hydrophilicity/hydrophobicity, or surface charge can also reduce the effects of fouling. Methods which reduce concentration polarization, such as using higher axial flow velocities, lower flux membranes, or turbulence promoters, also help to reduce fouling.

At the highest investigated pH, the inclusion of ternary uranyl-carbonate surface species overcompensates the carbonate sorption in Arnold et al., 1998 and yields too much sorption. Most probably a strong competing surface species is missing.

Transfer of a substance from a solution to a solid phase is called sorption. The most important sorbent used iu waste treatment is activated carbon. Activated carbon can also be applied to pretreatment of waste streams going into other processes in order to improve treatment efficiency and reduce fouling. Activated carbon sorption is most effective for removing from water organic materials that are poorly water-soluble and that have high molecular masses. 

The TLM offers a more comprehensive description of the solid-solution interface ([48] and references therein). For this reason Smith [48] determined TLM parameters to describe Pb, Cd and Zn adsorption in a recycled iron bearing material that is treated as a hydrous oxide in aqueous solution. Sarkar et al. [49] applied the TLM to represent the adsorption of Hg by quartz and gibbsite. Villdobos et al. [50] also used the TLM to model carbonate sorption...

Activated Carbon Sorption Activated carbon, such as powdered activated carbon (PAC) or granular activated carbon (GAC), is a commonly used adsorbent for the removal of several water contaminarrts. Adsorption on activated carbon depends on the intrinsic properties of the activated carbon sorbent (surface area and charge, pore size distribution, and oxygen corrtent) and on its solute properties (shape, size, charge, and hydrophobicity). 

The silver cation sorption by nanocarbon from the silver nitrate was investigated. It is established that the nanocarbon sorption capacity by Ag" amounts to 0.69 g/g which 30 times exceeds the activated carbon sorption capacity by Ag+ [4].
