The mud solution was isolated from mud in Ulziit lake and have been determined their chemical composition. Mud solution was obtained by pressing method, water soluble by extracting with water.Yield of solution (in natural mud) was 18.1%, yield of water extract was 17.05%, dry residue in mud solution and water extract were 18.37% and 17.96%, respectively.In mud solution were anions with following concentration: Cl- (52895 mg/l), SO42-(2650 mg/l), NO2- (11.2 mg/l), NO3-(0.0 mg/l), HCO3- (1830 mg/l), kations with following concentration: NH4+- (2.4 mg/l) , Fe3+-(0.0 mg/l), Fe2+-(0.0 mg/l); in water extract were anions with following concentration: Cl- (36476 mg/l), SO42-(2100 mg/l), NO2- (0.0 mg/l), NO3-(0.0mg/l), HCO3- (1982.5 mg/l) kations with following concentration: Ca2+(400.8 mg/l), Mg2+(8208 mg/l), NH4+- (2.1mg/l) , Fe3+-(0.0 mg/l), Fe2+-(0.0 mg/l). The content of macro and microelements in mud solution was 0.0003->3%.The mud solution of Ulziit lake was extracted by chloroform and investigated by chromato-mass-spectral method. This analysis shows that mud solution contains hydrocarbons 14.87%, dialkylphtalates 48.15%, organic acids 36.97%, respectively.
