Graphitic carbon nanocapsules, nanosheets and nanoplates were selectively obtained via a solid-state pyrolysis route from various ion-exchange resin-iron complexes.

Metal detoxification of waste water and industrial effluents are of increasing importance to industrialization in the twenty first century. The ability of coconut (cocos nucifera L) coir dust (CD), carbohydrate toluenediisocyanate resin (CTR) and sulphonated toluenediisocyanate resin (STR) to remove Pb(II) ions from aqueous solution by ion exchange was studied. Percentage ion exchange efficienc...

A method for growing Streptomyces griseus LP-16 in fermentors and extracting and purifying geosmin, using an ion-exchange resin, is described.

A study of regeneration of the ion exchange resins using a sub-critical mixture of CO2-H2O solution was reported. The experimental data were obtained by measuring the outlet concentration of ions Cd eluated from a column packed with a commercial ion exchange resin Amberlite IRC-86 until the effluent reached the input concentration. The adsorption isotherm was also reported. The correlation of t...

An ion-exchange chromatographic procedure has been developed for the separation and fluorometric detection of the urinary polyamines 1,3-diaminopropane, putrescine, spermidine, cadaverine, and spermine. The polyamines were separated on a 15 x0.45 cm cation-exchange column (70”) employing a combined pH-salt gradient. The separation conditions were designed to enable utilization of the sensitive ...

Ion chromatography (IC) developed by Small et al . [1] is widely recognized as a simple, powerful and convenient analytical technique for the determination of various low−molecular−weight ionic compounds [2, 3]. Firstly, IC with conductimetric detection (IC−CD) was mainly applied for the determination of inorganic anions. This is because a lightly sulfonated styrene−divinylbenzene co−polymer (S...

1,8-Dihydroxy-2-(imidazol-2-ylazo)-naphthalene-3,6-disulphonic acid (imidazol-azo-chromotropic acid IACA) was immobilized onto the anion exchange resin Dowex 1-X8, 50-100 mesh. The aim of this work was to investigate the mechanism of the complex formation between Pd(II) and immobilized IACA by following the absorption spectra of the solid phase. The reaction between Pd(II) and immobilized azo-d...

Recycling treatment of cable insulation resin generated from electric wires and cables was investigated. Conventional insulation PVC contains a lead component, tribase, as a thermal stabilizer and lead removal is necessary to recycle this PVC as insulation resin. This paper describes a solid surface adsorption method using ion exchange resin to remove the fine lead containing particles from PVC...
