It was aimed to remove the inorganic ions Mg²⁺ and Ca²⁺ (Excess of; Mg²⁺ and Ca²⁺ ions make water hard and cause to serious healt problems) organic substance cholest (its removing is important as  by means of health and cosmetically) from the solution by adsorption method using the active surfaces of Tutmac clay was charactized by XRD. The amount of the substances adsorbed on the clay surface in the solutions were analyzed using AAS and UV spectroscopic methods. The experimental data have indicated that Tutmaç clay is good adsorbent and physical adsorption methot is quite suitable for the removing of Mg²⁺, Ca²⁺ and cholesterol from solutions. The adsorption data determined from experimental results best fitted Langmuir Isotherms. The obtained results also confirmed that the applicability of Tutmaç clay is an efficient supporter material for removing contaminations of inorganic and organic substances. And Tutmaç clay material can be used as a very effective adsorbent in removing of pollutants from organic and aqueous solutions. https://www.biotech-asia.org/vol16no4/a-study-on-removing-of-some-organic-and-inorganic-substances-using-the-tutmac-clay-via-adsorption-method/ Calcium; Cholesterol; Kinetic of Adsorption; Solutions; Magnesium
