New N‐halamine polymeric compounds were prepared by reacting cyanuric acid and polyacrylonitrile. Grafting of acrylonitrile monomer onto cotton linters was carried out and the product was reacted with cyanuric acid and finally was chlorinated. Cyanoethylation of polyvinyl alcohol was performed using acrylonitrile monomer to give polyvinylcyanoethyl ether, which, in turn, was reacted with cyanuric acid. The biological activity of the various chlorinated compounds obtained was examined against Gram (+) and Gram (−) bacteria using columns and dishes methods. A high disinfecting power of the chlorinated compounds obtained was observed. Thus, the bacteria was deactivated after the first cycle without contact with the product. All of the compounds prepared were insoluble in water and most of inorganic solvents. These compounds were also found to be very stable and did not decompose to give any toxic compounds. Thus, the chlorinated compounds prepared had no harmful effects on humans.

AbstractA series of novel halamine polymers known as pyrimidinone biocidal polymers were prepared by reacting poly-4vinylacetophenone with urea and benzaldehyde to form 1H,3H,6H,-4(4 0 -polystyreno)-6-phenyl-pyrimidin-2-one, which on chlorination yielded 1Cl,3H,6H,-4(4 0 -polystyreno)-6-phenyl-pyrimidin-2-one. The same reaction was also carried out using the derivatives of benzaldehyde such as p-nitrobenzaldehyde and p-methoxybenzaldehyde under the same reaction conditions. . Electronic access

A B S T R A C TChelating resin bearing iminodiacetate function was prepared through subsequent treatment of poly(acrylamide-co-N,N´-methylenebisacrylamide) by ethylenediamine and sodium chloroacetate, respectively. The prepared resins were characterized using Fourier transform infrared spectroscopy. The different factors affecting the metal ions adsorption of this chelating resin such as solution pH, metal ions concentration, contact time, and adsorption temperature were studied in batch method. The prepared chelating resin showed a significant uptake performance towards Pb(II), Zn(II), Mn(II), and Cd(II) ions. Sorption capacities were found to be 1.7, 1.5, 1.6, and 1.77 mmol/g resin for Pb(II), Zn(II), Mn(II), and Cd(II), respectively. Equilibrium data were analyzed using the Langmuir, Freundlich, and Temkin isotherms. The results showed that the adsorption process was well described by Langmuir isotherm model. The kinetic and thermodynamic parameters of the adsorption process were estimated. These data indicated that the adsorption process is spontaneous and followed the pseudo-secondorder kinetics. Also, the removal of metal ions from aqueous solutions using iminodiacetate chelating resin in fixed-bed column was studied. Regeneration of chelating resin loaded with metal ions was successfully performed and the resin could be used repeatedly for five times with a small decrease in adsorption capacity.
