POSSIBILITIES OF OBTAINING SYNTHETIC ZEOLITE FROM LOCAL RAW MATERIALS OF TURKMENISTAN
Annotation
Zygophyllum fabago, commonly known as Syrian bean-caper or bean-caper, is a member of the Zygophyllaceae family. It is a perennial shrub found in arid and semi-arid regions. Known for its resilience in harsh conditions, Z. fabago has been traditionally used in folk medicine for treating a variety of ailments, including inflammation and digestive disorders. Recent studies focus on its phytochemical constituents and antimicrobial properties, revealing its potential as a source of bioactive compounds.
Key words:
Zygophyllum fabago, traditionally, medicine, inflammation, phytochemical constituents.
The progressive reform of industrial sectors and the introduction of new technologies should aim at creating advanced technological structures. These include the application of nanotechnologies, innovative solutions, and sharing the latest achievements in fundamental and applied sciences, ensuring the novelty of scientific approaches.
This research focuses on the possibilities of producing various types of synthetic zeolites using local raw materials available in Turkmenistan. These synthetic zeolites are critical for several industrial applications, including removing heavy metals from water, acting as catalysts in different industrial sectors, and improving concrete production processes.
One of the most popular methods for synthesizing synthetic zeolite involves using local raw material kaolin (Al2(Si2O5)(OH)4). This production method includes several stages:
First Stage: Kaolin is treated with a sodium hydroxide (NaOH) solution, resulting in the formation of sodium metasilicate (Na2SiO3) and the precipitation of aluminum hydroxide (Al(OH)3).
Second Stage: The mixture is heated in a specialized furnace at 800°C for 45 minutes, dissolved in water, and filtered. The filtered solution takes on a slightly reddish color.
Third Stage: The filtered solution is cooled and kept in clean water for one hour before undergoing another filtration process.
Fourth Stage: The filtered solution is stored at room temperature for one day, washed with clean water, and filtered.
Fifth Stage: The solution is transferred to a polyethylene container and heated at 90°C.
Sixth Stage: The heated solution is washed with clean water, filtered, and then placed in an oven at 110°C. This final process results in the production of synthetic zeolite in the 4A form.
Objective of the Research
The main objective of this study is to synthesize 4A-type synthetic zeolite from locally available kaolin in Turkmenistan and to develop a technology for using the resulting product to remove heavy metals from water, contributing to environmental protection.
Innovation of the Research
This work highlights the opportunities for synthesizing synthetic zeolite using locally available raw
materials. It also focuses on developing environmentally friendly products through innovative chemical and digital technologies, aligning with modern ecological and industrial needs while advancing the chemical sciences and new chemical technologies.

WATER PURIFICATION SYSTEM USING PHYSICAL METHODS
Abstract
This article examines physical methods of water purification, emphasizing their principles, key techniques, and applications. Sedimentation, filtration, adsorption, centrifugation, and UV disinfection are highlighted as effective approaches to removing impurities and microorganisms. Physical methods are valued for their simplicity, cost-effectiveness, and environmental benefits. However, limitations such as the inability to remove dissolved contaminants necessitate complementary treatment technologies. These methods remain fundamental in providing clean water for drinking, industrial, and agricultural purposes.
