INTRODUCTION Accurate and precise determination of inorganic As (III/V) redox species is important in the interpretation of its toxicity and mobility in acid mine waters. Several analytical methods use arsine generation to separate arsenic species but high metal concentrations can suppress arsine production (Creed and others 1996). The potential inhibition of arsine formation by eleven metal sp...

Ondansetron Hydrochloride (ODH) is 5-HT3 receptor antagonists and is used for pediatric formulation. It is an antiemetic drug given in treatment of nausea and vomiting. The bitter taste of the drug and having shorter half-life and needed frequent administration which reduces patient compliance. Hence, need was felt to deliver ODH to the patients, once a day to improve the patient compliance of ...

About 60–70% of the organic matter contained by domestic wastewater is formed by lipids and proteins. The microorganisms that are able to degrade this organic matter produce hydrolytic enzymes that cannot be produced by standard cultivation techniques. The extraction methods have to include detergents or ionic exchange resins to recover qualitatively and quantitatively the enzyme activity. In t...

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...

D/H exchange reactions at C2, C4 and C5 of the imidazolium cation were observed in catalytic hydrogenation reactions promoted by classical Ir(I) colloid precursors and [Ir(0)](n) nanoparticles dispersed in deuterated imidazolium ionic liquids indicating the participation of carbene species in this media. However, no D/H exchange reaction was observed in cyclohexene hydrogenation promoted by iri...

Abstract FR-4 epoxy resin is a common material used as internal parts in high voltage switchgear. In this paper, we adopted the accelerated thermal aging method to explore behavior of resin, simulating practical application switch. The effects on thermodynamic properties and decomposition characteristic gases were characterized by FT-IR, DSC, TG GC-MS analyses. experiment results showed that co...

There are a number of reports in the literature regarding the use of ionexchange materials for the catalytic hydrolysis of esters, proteins, and sucrose (1, 2, 3, 6, 7). The work of BODAMER and KUNIN (1) on the hydrolysis of sucrose by several readily available synthetic cation exchangers suggested that it might be possible to use this method for the determination of the total sugars in plant s...

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...
