we describe a rapid, simple, and reliable procedure for routine isolation of mycobacterium leprae dna from slit-skin swab specimens. this one-step dna extraction method is based on the utilization of chelexr 100, a chelating ion exchange resin. slit-skin swab specimens from seven untreated leprosy patients at baba baghi leprosy hospital in iran were processed by this procedure. the polymerase c...

A new chelating resin was prepared by coupling Amberlite XAD-4 with alizarin red-s through an azo spacer, characterized by infra-red spectroscopy and thermal analysis and studied for Rh(III) preconcentration using inductively coupled plasma atomic emission spectroscopy (ICP-AES) for rhodium monitoring in the environment. The optimum pH for sorption of the metal ion was 6.5. The sorption capacit...

a chelating resin is prepared by condensation polymerization of aniline with formaldehyde andcharacterized by ft-ir, elemental analysis and studied for the preconcentration and determination of traceplatinum ion from environmental water sample using inductively coupled plasma-atomic emission spectroscopy(icp-aes). the optimum ph value for sorption of the metal ions was 5. the maximum adsorption...

Amberlite XAD-4 was covalently linked with octa-O-methoxy resorcin[4]arene through N=Nto form chelating resin, which has been duly characterized and successfully used for separation and preconcentration of rareearth metal ions like U(VI), Th(IV), La(III) and Ce(III). Various physiochemical parameters like pH, flow rate, sorption capacity, breakthrough studies, distribution coefficient, preconce...
