Abstract

In somepartoftheworld,groundwatersourcecanbecomeunsafe for drinkingduetothehighconcentrationof fluoride ions[1]. The low costandfacile-producedadsorbentlikepalmstonecould effectivelyremoved fluoride ionsthroughadsorptionprocess.In this dataset,theinfluence of fluoride ionconcentration,solution pH, adsorbentdosage,andcontacttimeon fluoride ionadsorption by palmstoneswastestedbycentralcompositedesign(CCD) under responsesurfacemethodology(RSM).Thedatastonecar- bonized adsorbentwaspreparedbyasimpleandfacilemethodat relativelylowtemperatureof250 °C during3h.Theadsorbenthad the mainfunctionalgroupsofO–H, –OH, Si–H, C¼O, N¼O, C–C, C– OR, C–H, andC–Br onitssurface.Attheoptimizedconditions obtained byRSM,about84.78%of fluoride ionwasremovedusing the adsorbent.TheLangmuirisothermwassuitableforcorrelation of equilibriumdata(maximumadsorptioncapacity¼ 3.95 mg/g). Overall,thedataofferafacileadsorbenttowaterandwastewater workswhichfacetohighlevelof fluoride water/wastewater content.
