Claim 8:
9. A process of making a chitosan (CS)-doped Strontium oxide (SrO) nanocomposite nanocomposite, consisting of;
mixing water and a strontium chloride hexahydrate and stirring the mixer for 2 hours to make a solution of the strontium chloride hexahydrate;
forming a precipitate of a strontium chloride hexahydrate nanoparticle in solution by adjusting a pH of the solution of strontium chloride hexahydrate to a specific pH by adding sodium hydroxide solution for 2 hours and stifling;
collecting a pellet strontium chloride hexahydrate nanoparticle by centrifuging the a strontium chloride hexahydrate nanoparticle in solution;
making a powder of strontium chloride hexahydrate nanoparticle by heating the pellet of the strontium chloride hexahydrate nanoparticle at 120° C. for 24 hours;
preparing a strontium chloride hexahydrate nanoparticle solution using the powder of strontium chloride hexahydrate nanoparticle in distilled water and adding a specific concentrations of a chitosan solution to create a chitosan (CS)-doped Strontium oxide (SrO) nanocomposite; and
purifying water by reducing a pollutant content in water by adding the CS-doped SrO nanocomposite in presence of a reducing agent at a second specific pH.
