Ayrim mineral moddalarni plazmali induktiv bog‘langan atom emission spektormetr usulida tadqiq qilish

Atom emissiya spektral tahlili (AESA) - 150-800 nm to‘lqin uzunligi diapazonida gaz fazasidagi erkin atomlar va ionlarning emissiya spektrlarini o‘rganishga asoslangan elementar tahlil usuli. Usulning ishlash prinsipi har bir kimyoviy elementning atomlari qat’iy belgilangan rezonans chastotalariga ega ekanligiga asoslanadi, buning natijasida ular yorug‘likni chiqaradi yoki yutadi. Radiatsiyaning yuqori barqarorligi, tezkor o‘lchovlar, kalibrlashning qulayligi, makro va mikrokomponentlarni bir vaqtning o‘zida ko‘p elementli aniqlash imkoniyati, tahlil usulini tez joriy etishga olib keldi. Shu usulda buyrak toshi analiz qilinganda buyrakda Vevellit (kalsiy oksalat monogidrat) CaC2O4.H2O, Veddellit (kalsiy oksalat digidrat), CaC2O4.2H2O, Brushit CaHPO4.2H2O, Struvit MgNH4PO4.6H2O tarkibli minerallar ko‘rinishida uchraydi makroelementlar jarrohlik yo‘li bilan ajratib olingan buyrak toshida makro elementlar bilan bir qatorda mikro elementlar, og‘ir metallar ham aniqlandi. 376 mg/l kalsiy elementi bo‘lsa, undan 2.82 martta kam fosfat ioni, 35.1 kam rux elementi, 94 marta kam natriy metali borligi ma’lum bo‘ldi.Og‘ir metallardan eng kami simob elementida kuzatildi.Mos ravishda mis va qo‘rg‘oshin 4.07 va 6.85 marta simobdan ko‘p ekanligi ma’lum bo‘ldi.

Atomic emission spectral analysis (AESA) is a method of elemental analysis based on the study of emission spectra of free atoms and ions in the gas phase in the wavelength range of 150-800 nm. The principle of operation of the method is based on the fact that the atoms of each chemical element have fixed resonance frequencies, as a result of which they emit or absorb light. High stability of radiation, rapid measurements, ease of calibration, simultaneous observation of macroand micro components. The ability to determine p elements led to the rapid introductionof the analysis method. When analyzing kidney stones in this way, Vevellite (calcium oxalate monohydrate) CaC2O4.H2O, Weddellite (calcium oxalate dihydrate), CaC2O4.2H2O, Brushite CaHPO4.2H2O, Struvite MgNH4PO4.6H2O are found in the kidney. macroelements found in the form of minerals, microelements and heavy metals were also detected in kidney stone extracted by surgery. It was found that there is 376 mg/l calcium element, 2.82 times less phosphate ion, 35.1 times less zinc element, and 94 times less sodium metal. Among the heavy metals, mercury element was the least. Copper and copper respectively. It turned out that lead is 4.07 and 6.85 times more than mercury.
