INTRODUCTION
The protection of the ecology of the Fergana region requires a reduction in the formation of solid waste at industrial enterprises, including waste oiled and waxed clay adsorbents and their burial in country dumps.
We have developed a method for the regeneration of spent oily and waxed adsorbents by treating them with a surfactant-containing aqueous solution, the cost of which mainly depends on the price of the latter.
DISCUSSION AND RESULTS
It is known that today effective surfactants are imported to enterprises mainly from abroad at a high price.
Therefore, the creation and application of compositions of water-soluble surfactants from local raw materials is considered an urgent and economically important task.
In this aspect, the fatty acids of cottonseed stock are considered to be a cheap raw material for the production of surfactants. in Uzbekistan, their production has been mastered at 18 large oil and fat enterprises.
Treatment of raw (or distilled) fatty acids with alkaline reagents will make it possible to obtain their salts, which are readily soluble in water [1]. However, detergent, foaming, wetting and other colloid-physical properties of such solutions do not always meet the requirements of consumers, which is due to the composition and content of the processed material.
Waste oiled and waxed clays are considered to be multicomponent highly dispersed materials, and their regeneration with an aqueous solvent requires the use of special surfactant compositions, mainly obtained from local components.
By saponification of raw fatty acids of cotton soapstock, first with sodium sulfite, then with triethanolamine (TEA), a liquid detergent base for the created surfactant composition was obtained [4].
The physicochemical parameters of the obtained surfactants were analyzed by standard methods [6].
Table 1 presents the main physico-chemical parameters of the obtained basis of the surfactant composition.

From Table. 1 it can be seen that with an increase in the mass fraction of fatty acids, the color of the surfactant base darkens, and the mass fraction of free carbonic soda and impurities that are insoluble in water increase. This also increases the initial foam volume (from 200 ml to 300 ml). Moreover, with an increase in the mass fraction of fatty acids in the resulting base, the content of free caustic alkali decreases from 0.15 to 0.12%.
CONCLUSION
In practice, to increase the effectiveness of surfactants, their compositions are more often used. the latter are superior in their colloid-chemical properties to individual washing bases.
With this in mind, a number of surfactant compositions have been created, essentially consisting of local raw materials.
Thus, the studies carried out and the results obtained make it possible to recommend the obtained compositions of surfactants for the regeneration of spent oily and waxed clay adsorbents.
