The removal of copper from aqueous solution by Amberjet 1500H, Amberjet 1300H and Amberlite IRC86 ion exchange resins is described. The Amberjet 1500H shows a remarkable increase in sorption capacity for copper compared to other adsorbents. The adsorption process shows maximum removal of copper in pure aqueous solution for an initial copper concentration of 5.98 mmol/L. The metal ions adsorptio...

Reduced bioavailability of nonpolar contaminants due to sorption to natural organic matter is an important factor controlling biodegradation of pollutants in the environment. We established enrichment cultures in which solid organic phases were used to reduce phenanthrene bioavailability to different degrees (R. J. Grosser, M. Friedrich, D. M. Ward, and W. P. Inskeep, Appl. Environ. Microbiol. ...

Ion exchange has a great potential to remove heavy metals from industrial wastewaters or heavy metal-containing sludge. In order to design and operate heavy metal removal processes, the equilibrium relationship between ions and resin must be known a prior. A series of ion-exchange equilibrium tests of Cu/H, Zn/H, and Cd/H systems using Amberlite IR-120 were performed. The equilibrium data were ...

• A portable procedure for determination of mercury and methylmercury is proposed. Anodic stripping voltammetry using a solid gold electrode adopted. Home-made cartridges containing new modified resin are Comparison between direct analyser made. measurement speciation inorganic (Hg IN ) (CH 3 Hg) was developed. sample pretreatment optimized to determine total content. home-made sorbent (CYXAD, ...

During 1950-3 Segal and his colleagues (Segal, 1951 ; Segal, Miller, and Morton, 1950, 1952, 1953; Segal, Miller, Morton, and Young, 1950) have published the results of their investigations of the hydrochloric acid content of the gastric juice by an original method which does not require the passing of a Ryle's stomach tube. This elegant technique depends upon the power of the hydrogen cation (...
