The Use Of Radio-Isotope Tracing In Analytical Chemistry

The use of radio-isotope tracing in studying the sight of intact pollutants in the environment Supervised by: Dr. Mhasen By: Amany Ayman Ali Aboulrous (pre-master student) depute of thoroughgoing pollutant = its tape drive + its transformation What does this sentence flirt with??? This means that the determination of fate of constitutive(a) pollutants divides into two separate: 1- Determination of appliance of transport and/or how more involving in transport process. 2- Determination of mechanism of transformation and/or how much (or what) the product. Radio-isotope tracing: Principle: The dynamical atoms are recognized by their radiation and, being stanch companions of the inactive atoms of an element, they serve 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 ---- > 1 4C6 + 1P1 2- throw up it in fitting form: Ba 14CO3 ----- > 14C6 3- Radiolabelled compounds are synthesized by appropriate radiochemical organic synthesis reactions: e.g.: labelled nonyl phenol: Ba 14CO3 ------ > 14C6H5OH ------ > C9H1914C6H4OH Analytical methods for detective work radio-labeled compounds: 1- Gas-filled detectors: e.g.: Geiger-Müller detector 2- Autoradiography (e.g. for Thin Layer Chromatography): Is image on roentgen ray film produced by the pattern of decay emissions. 3- glistering detectors: e.g.: fluid Scintillation Counting (LSC) The environmental applications of radioisotopes tracing: The environmental obstacle : (1) mass balance is missing (A) Fate of nonylphenol (NP) in a lab-sca! le membrane bioreactor (MBR) [1] This study aimed at giving a bless insight into the possible fate of nonylphenol (NP) during...If you want to get a full essay, order it on our website: OrderEssay.net
