| Summary: | Synthesisofcement-zeolitecompositegranulesandtheadsorption-desorptiontestofethanol/watermixturehavebeensuccessfullyconducted.Cement-zeolitecompositegranulesweremadebymanuallystirringthemixtureof5gramsofnaturalzeolite,2gramsofportlandcement,and4mLofdistilledwaterinaporcelaindisk.Thesuspensionwasformedasgranulesandwasallowedtobedryatroomtemperaturein5days.Cement-zeolitegranuleswerecharacterizedusinginfraredspectroscopy(FTIR)andX-raydiffraction(XRD)methods.Thecompressivestrengthofcement-zeolitecompositegranuleswasdeterminedusingmaterialtestingmachine.Adsorptioncapacitytestwascarriedoutbysoakingcompositegranulesinwaterfor24hoursandthencalculatingtheweightdifferenceofcompositeganulesbeforeandaftersoaking.Adsorptionanddesorptiontestwereconductedbydropping1mLethanol-watermixturewithvariousconcentrations(99.9%,90%,80%and75%(v/v))ofethanoloncompositegranulesanditsadsorption-desorptiontimewasthennoted.
