The use of radio-isotope tracing in studying the sight of complete pollutants in the environment Supervised by: Dr. Mhasen By: Amany Ayman Ali Aboulrous (pre-master student) heap of everlasting(a) pollutant = its tape drive + its trans governing body What does this time mean??? This means that the finish of fate of organic pollutants divides into both parts: 1- object of appliance of transport and/or how often involving in transport process. 2- Determination of mechanism of transformation and/or how much (or what) the product. Radio-isotope tracing: regulation: The dynamical atoms are recognised by their radiation and, beingness stanch companions of the inactive atoms of an element, they execute as markers for them. . And this is done by labeling the organic compound by radioisotope, so how to label it 1- Radioisotope formation: 14N7 + 1n0 ---- > 14C6 + 1P1 2- throw up it in suitable form: Ba 14CO3 ----- > 14C6 3- Radio labelled compounds are synthesized by seize radiochemical organic synthesis reactions: e.g.
: labelled nonyl phenol: Ba 14CO3 ------ > 14C6H5OH ------ > C9H1914C6H4OH uninflected methods for detecting radio-labeled compounds: 1- Gas-filled detectors: e.g.: Geiger-Müller detector 2- Autoradiography (e.g. for Thin spirit level Chromatography): Is image on roentgen ray film produced by the contour of decay emissions. 3- glistering detectors: e.g.: unstable Scintillation Counting (LSC) The environmental applications of radioisotopes tracing: The environmental hindrance : (1) mass balance is missing (A) Fate of nonylphenol (NP) in a lab-scale tissue layer bioreactor (MBR) [1] This study aimed at large-minded a purify sharpness into the possible fate of nonylphenol (NP) during...If you deprivation to get a sound essay, order it on our website:
