Статья посвящена актуальной проблеме утилизации твердых бытовых отходов (ТБО). Предложен способ переработки органической части ТБО в удобрения, содержащие в своем составе как органические (~40%), так и минеральные (~60%) компоненты, т.е. представляющих собой аналог органоминеральных удобрений. Ввиду наличия в сырых бытовых отходах патогенной микрофлоры невозможно их использование без предварительного обезвреживания. Рассмотрена возможность использования геотермальных вод Азербайджана, выходящих на поверхность с температурой 25-75°С и содержащих сероводород, для борьбы с патогенной микрофлорой органической составляющей ТБО. Способ предусматривает обработку органической части ТБО геотермальными водами и введение природных добавок местного происхождения. Для внесения микроэлементов к органической составляющей ТБО добавляют фонолит, для регулирования рН полученного удобрения используют ракушечник. Изучено влияние присутствия НS в геотермальных водах на эффективность обеззараживания используемого сырья. Обоснована роль растворенного в геотермальных водах сероводорода в повышении эффективности обеззараживания. The article is devoted to the problem of solid household waste disposal. A procedure is proposed for convering the organic part of solid household waste into fertilizers containing both organic (~40%) and mineral (~60%) components, i.e. representing an analogue of organomineral fertilizers. Due to the presence of pathogenic microflora in raw household waste, it seems unreasonable to use it without preliminary detoxication. A possibility is considered of using geothermal waters of Azerbaijan, coming to the ground surface with a temperature of 25-75°C and containing hydrogen sulfide, for disinfection of the pathogenic microflora of the organic ingredients of the solid household waste. The method involves treating the organic part of the waste with geothermal water followed by introducing natural additives of the local origin. For introducing micronutrient elements, a phonolite is added to the organic component of the waste, and a local shell limestone is used for regulating pH level of the resulting fertilizer. The influence of НS presence in the geothermal waters on the efficiency of disinfection of the raw materials is studied. The role of hydrogen sulfide dissolved in the geothermal waters in increasing the efficiency of disinfection is substantiated.

The interaction of cobalt (II) and nickel (II) with 2-hydroxy-5-nitrothiophenol (HNTPh) and diphenylguanidine (DPG) produces chloroform-extracted mixed-ligand complexes (MLC) with the ratio Me (II): GNTF: DPG = 1: 2: 2. Conditions for extraction-photometric determination of cobalt (II) nickel (II) are revealed. It found that MLC are formed in a weakly acid medium (pH opt

In this paper we studied the interaction of uranium (VI) with with dithiolphenols (2,6‐dithiophenol, 2,6‐dithiol‐4‐methylphenol, 2,6‐dithiol‐4‐ethylphenol, 2,6‐dithiol‐4‐tert‐butylphenol), and hydrophobic amines by absorption spectroscopy method. The sudied hydrophobic amines are aniline, N–methylaniline, N,N–dimethylaniline, diphenylguanidine, triphenylguanidine, benzylamine, phenantrolin, dipyridyl, p‐aninopyridin, 2‐(N,N‐dimethylaminomethyl)‐4‐methylphenol and 2‐(N,N‐dimethylaminomethyl)‐4‐bromphenol. The optimal conditions for the formation and extraction of ionic associates were found and the ratios of components in the complexes were established. It was found that associates are formed in a weakly acidic medium (pHopt = 3.5‐7.1). The maxima in the light absorption spectra are observed at λ = 434‐478 nm. Molar coefficient of absorption is equal ε = (2.65‐3.62)•104. On the basis of the obtained data, photometric methods of uranium determination in various objects have been developed.
