Abstract:
Medicinal muds, so called Peloids in the last decade attract attention in many countries as effective means for the treatment- preventive, and perfumery-cosmetic purposes. It has been established that the possibilities of this formation of nature are not limited to the many-year experience of the mankind. In terms of further improvement of the human social sphere, nowadays peloids are referred to as XXI century material. The aim of the research was to study the physical-chemical characteristics, such as: humidity, pH, ash content, bulk (volumetric) density and organoleptic properties of sulphide silt peloids of some Adjara region lakes, as well as to determine the content of mineral and organic compounds (humic and organic acids). The objects of the study were the sulphide silt peloids of some Adjara region lakes: Mtsvane, Gasaliani, Shratiani, Nurigeli, Ardagani and Niphi. The main good quality indicators of the sulphide silt peloids have been determined according to the methods described in the State Pharmacopoeia XI. The mineral and organic compounds in the research objects have been determined using the modern instrumental methods of analysis described in the literature. Based on the performed studies, the main physical-chemical characteristics of sulphide silt peloids of some Adjara region lakes (Mtsvane, Gasaliani, Shratiani, Nurigeli, Ardagani and Niphi) have been studied and their mineral contents (Ca-Na Feldspar, K Feldspar, Ca- Montmorillonite, Hematite, Quartz, Magnetite, Chlorite) determined. By the spectrophotometric and gravimetric methods of analysis there is established, that the sulphide silt peloids of the lakes Ardagani (1,22%), Niphi (1,72%) and Gasaliani (1,33%) are distinguished by relatively higher content of humic acids. By the Gas Chromatography-Mass Spectrometry - method of analysis, in the study objects there is established the content of complex ethers of the following organic acids: Stearic, Palmitic, Caprylic, Myristic, Valeric, Lauric, Oxalic, Phthalic and Fumaric acids.
