KOMBINASI BATU PASIR-BENTONIT TERAKTIVASI SEBAGAI ADSORBEN ANION Cr(VI) PADA AIR LINDI TEMPAT PEMBUANGAN AKHIR (TPA) SAMPAH
ThisÂ researchÂ isÂ conductedÂ toÂ knowÂ optimumÂ conditionsÂ andÂ absorptionÂ efficiencyÂ ofÂ combinatedÂ natureÂ bentonite-limestoneÂ asÂ anionÂ adsorbentÂ Cr(VI)Â inÂ lindiÂ ofÂ garbage.Â BatchÂ methodÂ wasÂ usedÂ inÂ thisÂ research,Â andÂ adsorbentÂ wasÂ activatedÂ usingÂ H2SO4Â andÂ heating.Â TheÂ resultÂ showsÂ thatÂ absorptionÂ efficiencyÂ Cr(VI)Â inÂ lindiÂ garbageÂ usingÂ combinatedÂ natureÂ bentonite-limestoneÂ isÂ 86.85%.Â OptimumÂ conditionÂ ofÂ absorptionÂ achievedÂ usedÂ adsorbentÂ thatÂ haveÂ activatedÂ withÂ H2SO4Â 1.6Â MÂ andÂ heatedÂ temperatureÂ 140Â°C.
Keywords:Â combinatedÂ natureÂ bentonite-limestone,Â lindi,Â absorptionÂ efficiency
