Many technological solutions contain valuable components as waste and can become an additional source of rare earth elements to meet the needs modern production. The development technologies based on commercially available cheap sorbents opens up possibility extracting from various solutions. aim this work is study effect process sorption cerium ions corresponding sulfates by individual Amberli...

The removal of heavy metal ions from wastewater by sorptive flotation using Amberlite IR120 as a resin, and column, was investigated. A combined two-stage process is proposed an alternative the metals aqueous solutions. first stage sorption onto followed dispersed-air flotation. on depending contact time, pH, resin dosage, initial concentration studied in batch method .Various parameters such a...

BACKGROUND Recent technical developments using solid-state technology have enabled rapid image acquisition with single photon emission computed tomography (SPECT) and have led to a renewed interest in technetium-99m-teboroxime (Tc-99m-teboroxime) as a myocardial imaging agent. Tc-99m-teboroxime has demonstrated high myocardial extraction, linear myocardial uptake relative to flow even at high f...

Raw-starch-digesting enzyme (RSDA) was immobilized on Amberlite beads by conjugation of glutaraldehyde/ polyglutaraldehyde (PG)-activated beads or by crosslinking. The effect of immobilization on enzyme stability and catalytic efficiency was evaluated. Immobilization conditions greatly influenced the immobilization efficiency. Optimum pH values shifted from pH 5 to 6 for spontaneous crosslinkin...

We evaluated the competitive fitness of three phenanthrene-mineralizing isolates that were provided with nonsorbed or sorbed phenanthrene in competition experiments. One isolate had a clear advantage when presented with Amberlite IRC-50-sorbed phenanthrene, yet none were favored when presented with nonsorbed or Amberlite XAD-7-sorbed phenanthrene. Our results indicate that contaminant availabil...

This work studies the feasibility of the use of a combined physical-biological remediation procedure for treatment of effluents contaminated with molinate, where the herbicide is removed through adsorption and biodegraded in a subsequent stage, with the regeneration of the adsorbent. In order to select the most adequate absorbent for molinate, different materials were tested, namely pine bark, ...

Uranium (VI) sorption using an anionic exchanger resin in the presence of sulfate anions, namely amberlite 910, was the subject of current study. Batch sorption experiments were carried out to evaluate the influence of operational parameters such as pH, contact time, initial concentration and existence of various anions (including phosphate, sulfate, chloride, fluoride, and nitrate) in the solu...
