Geochemistry and Geophysics

Subjects of the inquiry: different types of minerals, ores, sorts of industrial enterprises and manufactures and also standard samples of steels, colour metallurgy and other materials.
Aim of inquiry: elaboration of methods of amperometric and conductometric determination of the Pt(IV), Pd(II) и Au(III) by solution of thioacetamide on different by acid-base properties of phone electrolytes and buffer mixtures with high metrological characteristics and analytical parameters. Practical realization of elaborated electrochemical methods to analysis of some real natural objects and industrial materials.
Method of inquiry: potentiostatic culonometry, chemical methods,
conductometry, polayrographiya, voltamperometry, amperometric titration.
The results achieved and their novelty: voltamperometric behavour of thioacetamide and it's metallocomplexes on the platinium microdisk anode on different by nature and concentrations buffer solutions and phone electrolytes was investigated. Nature of limited anode currents and number of electronodonation oxidation of one molecule of thioacetamide were determinated and also the conditions of Pt(IV), Pd(II) и Au(III) determination by it's solution were optimized. On the base of obtained data the possibility of using of elaborated electrochemical methods to analysis of some real objects and industrial materials was shown.
Practical value: the possibility of amperometric and conductometric titration of Pt(IV), Pd(II) и Au(III) in model binary, triple and more complex mixtures imitating real natural objects and industrial materials by to using of different by nature and concentration phone electrolytes and buffer mixtures and high - sensitive reagent -thioacetamide was shown.
Obtained results have allowed to realize a choice of rational way of analysis of different by composition shlams, tails, standart samples and alloys, jewelry articles and others materials.
Degree of embed and economical effectivity: obtained experimental data by electrochemical titration of Pt(IV), Pd(II) и Au(III) by thioacetamide solution were tested and proposed to practical introduction in practices of analysis of laboratories Almalik mining - metallurgical combinate, Dehkanabad potassium facture of Kashkadarya region and also in educational process for bachelors and magistrs of inorganic and analytical chemistry of chemical faculty of NUUz after name M. Ulugbek, department on chemistry and chemical technology of Navoiy state mining institute, department of analytical chemistry of Samarkand state university after name A. Navoiy and department of chemistry-ecology and methodic of it's teaching of the Djizzak State pedagogical institute of the name A. Kodiriy.
Sphere of usage: analytical and physical chemistry, electrochemistry, protection of objects of environment, medicines, composition control of industrial materials and natural objects.
