The estimation of urinary catecholamines has assumed clinical significance mainly because of its value in the diagnosis of phaeochromocytoma (Engel and Euler, 1950; Euler, 1951). Since biological methods have obvious limitations for routine work, various chemical methods have been developed (Lund, 1950; Pekkarinen and Pitkanen, 1955; Euler and Floding, 1955a, b). They are based on the same prin...

The copper(II)-histidine complex obtained following dialysis of human plasma with histidine was investigated using various types of extraction systems and ion exchange resins. According to the results obtained, the Cu(II)-histidine complex formed under the dialysis conditions has one positive charge. Preconcentration of copper from the dialysis solution was achieved by its extraction as a dithi...
In this work, kinetics and thermodynamics of esterification reaction were studied. This research investigated the esterification reaction between methanol and acidified oil catalyzed by sulfonated cation exchange resin and proposed a new rate equation for consideration of kinetics of this reaction according to the Langmuir-Hinshelwood mechanism. Thermodynamics and kinetics parameters were calcu...
al.(12), I did not find the technique 12. Merlini J, Piro P, Pavesi F, et al. weakly basic resin Amberlite IRA-68 susceptible to technical artefacts. Detection and identification of monoclo(Rohm and Haas), which has a polyImmunofixation on cellulose acenal components: Immunoelectrophoreacrylic matrix, has practically no affintate deserves wider use for identifisis on agarose gel and immunofixat...
Wastewater discharged from metal-finishing processes usually contains nickel, a hazardous substance that is used extensively in the surface finishing industry. In the present study, an acidic solution containing nickel was treated using strong acid cation exchange resin. A continuous lab-scale cation exchange arrangement permitting the assessment of electric current as an enhancement mechanism ...
An oral controlled release suspension of chlorpheniramine maleate was prepared using ion-exchange resin technology. A strong cation exchange resin Indion 244 was utilized for the sorption of the drug and the drug resinates was evaluated for various physical and chemical parameters. The drug-resinate complex was microencapsulated with a polymer Eudragit RS 100 to further retard the release chara...
Some novel functional resins were developed for highly selective separation and/or determination of mercury, selenium, fluoride and hydrogen peroxide, by simple modification of common ion—exchange resin with appropriate reagents. These reagents should have three functional properties, namely selective reaction with the determinant of interest, an ion—exchange reaction with the resin and physica...
Renewable energy is an increasing need in our society. Microbial fuel cell (MFC) technology represents a new technology for the regeneration of electricity from what would otherwise be considered waste and can be a vital candidate for energy in this respect. Electricity directly generated by using bacteria while accomplishing wastewater treatment in MFC processes. The present study deals with p...
the main objective of this study was to investigate biocompatibility and provide in vivo pharmacological and toxicological evidence for further investigation of the possibility of ph sensitive ion exchange resin microsphere for clinical utilizations. acute toxicity study and general pharmacological studies were conducted on the ph sensitive ion exchange resin microsphere we prepared. the genera...
