The book shows principles and applications of the most distributed technique used for water analysis. The central laboratory of Greater Cairo Drinking Water Company (GCWC) uses this important technique and applies the analytical methods recorded in the standard methods for water and wastewater examination. This laboratory represents nucleus and origin of many reference laboratories of water analysis in Egypt. Wael Mahmoud and his team of the researchers modified the scientific cooperation between the central laboratory of GCWC and the national research centre. Wael and his team used the...

The book is intended as that introduction to the ICP-OES technique. It was written not only for those persons who have some familiarity with other analytical techniques such as atomic absorption spectrometry but also for novices in the field of analytical chemistry. The book begins with some simple, yet fundamental, concepts regarding atomic spectroscopy and the analytical techniques based on this field of study. As one progresses through the book, more detail regarding the ICP-OES technique is presented including information about ICP-OES performance, instrumentation and methodology. We...

Instrumental methods of chemical analysis have become the principal means of obtaining information in diverse areas of science and technology. The speed, high sensitivity, low limits of detection, simultaneous detection capabilities, and automated operation of modern instruments, when compared to classical methods of analysis, have created this predominance. Professionals in all sciences base important decisions, solve problems, and advance their fields using instrumental measurements. The book explains many details about one of the most important instrumental techniques used for different...

The book aimed to reveal degradation of Cucurbitacin E glucoside obtained from Citrullus colocynthis (L.) (Hanzal) into Cucurbitacin E and glucose by mean of microbial biotransformation using Curvularia lunata NRRL 2178 as a source of -glucosidase. All the instrumental data obtained by highly advanced techniques, confirmed the microbial conversion of cucurbitacin E glucoside into cucurbitacin E and glucose indicating effect of enzyme in the hydrolysis process by splitting of glucose from the anomeric carbon atom. The effect of the cucurbitacin E glucoside and cucurbitacin E on the...
