“…Up to now, many polymers, such as poly(vinyl alcohol) and sulfonated poly(vinyl alcohol), 8,9 poly(ammonium acrylate), 10 poly(acrylic acid), [11][12][13] polyethylenimine, 13-17 diethylaminoethyl cellulose, 18 poly(4-vinylpyridine) and poly(diallyl dimethylammonium) chloride, 21 poly(vinyl sulfonic acid), 22 partially ethoxylated polyethylenimine 23,24 and chitosan and pectin 15,25 have been used for metal removal from wastewaters. Nowadays, ultraand microfiltration methods for trace metals removal from waters by the addition of a watersoluble polymer into the aqueous solutions have become a significant research area.…”

As a result of its wide industrial applications, zinc has become an important contaminant in aquatic environment since it is a toxic heavy metal and some of its compounds such as zinc arsenate and zinc cyanide, may be extremely hazardous. Therefore, there is a growing need for developing simple methods capable of separating and recovering trace zinc from environmental waters. Nowadays, the ultra and microfiltration method for trace metals removal from waters by the addition of water-soluble polymers into the aqueous solutions has become a significant research area. The choice of watersoluble macroligands remains important for developing this technology. Sodium carboxymethyl cellulose (Na-CMC) was selected as complexing agent. The microfiltration experiments were carried out in stirred dead-end cell. To separate formed polymer-metal complex Versapor membranes were used. The concentration of heavy metal ions after microfiltration in aqueous solution was determined using atomic absorption spectroscopy (AAS). Effects of amount of complexing agent, pH value, type of anion, ionic strength and operating pressure on the flux (J) and rejection coefficient (R) were investigated. Experimental results indicate a considerable influence of the pH, ionic strength and type of anion on the rejection coefficient, while effect of amount of complexing agent is relatively insignificant. The Na-CMC used in the research proved to be very effective, which may be supported by the high rejection coefficients obtained (99%)

“…However, in all cases, RO membranes gave satisfactory results. The ultrafiltration ceramic and metallic membranes combined with water-soluble, chelatic polymers, binding small radioactive ions were described elsewhere [3]. The experiments Cshow that by use of such systems the rejection of radionuclides from the waste liquids may be as high as that achieved with RO modules.…”

The first step in the processing of low-and medium-level liquid radioactive waste is the reduction in the volume of liquid containing small concentrations of radionuclides. Various methods for concentration of radioactive waste have been studied and developed at the Institute of Nuclear Chemistry and Technology, including membrane processes. Reverse osmosis was implemented at the Radioactive Waste Management Plant. Other methods such as ultrafiltration, membrane distillation, adsorption and different integrated processes were studied in the scope of national and international projects.This paper presents the results of research performed at Institute of Nuclear Chemistry and Technology in Warsaw concerning radioactive liquid waste treatment and the programs of implementation of these methods at nuclear centers producing such wastes, as well as the plans for the utilization of the knowledge and experience and designs of schemes for radioactive waste management in future nuclear power industry. The integrated system developed on the basis of research will be a prototype for further implementation.
