Abstract
U ovom radu ispitana je regeneracija i višestruko korištenje prirodnog zeolita za vezanje cinka uzastopnim ponavljanjem više radnih ciklusa i ciklusa regeneracije postupkom u koloni. Kao uzorak korišten je Na-oblik prirodnog zeolita porijeklom iz nalazišta Vranjska Banja (Srbija). Rezultati su prikazani krivuljama proboja i krivuljama regeneracije. Integracijom područja iznad krivulja proboja i ispod krivulja regeneracije izračunate su količine vezanog i eluiranog cinka. Rezultati su pokazali da uzastopno ponavljanje ciklusa regeneracije nije dovelo do degradacije strukture zeolita koja bi utjecala na smanjenje količine vezanog cinka na zeolitu u radnom ciklusu. Nakon devet uzastopnih radnih ciklusa i ciklusa regeneracije zeolit nije u potpunosti iscrpljen te ima sposobnost provoñenja još dodatnih ciklusa. Zbrajanjem kapaciteta u točki iscrpljenja tijekom devet radnih ciklusa ukupno je uklonjeno 6,208 mmol cinka po gramu zeolita (ili 406 mg cinka po gramu zeolita), odnosno ukupno je obrañeno 43,99 l otopine cinka na istom sloju zeolita. Upravo ovi rezultati ukazuju na prednost postupka u koloni u odnosu na šaržni postupak pri obradi veće količine otpadne vode niže početne koncentracije cinkovih iona te ističe uzorak prirodnog zeolita kao „magični mineral“.
Abstract (english)
This paper investigated the regeneration and multiplies reuse of natural zeolite for zinc removal from aqueous solution by successive repeating of service and regeneration cycle in fixed bed. The Na-form natural zeolite originates from the Vranjska Banja (Serbia) deposit is used as a sample. The results are presented by breakthrough and regeneration curves. By integration of the area above the breakthrough curve and under the regeneration curve, the amounts of bound and eluted zinc were calculated. Results showed that successive repetition of regeneration cycle didn’t cause degradation of zeolite structure which may influence on reduction of zinc amount bound on zeolite in service cycle. After nine successive service and regeneration cycles, the zeolite bed hasn’t completely exhausted and still has abilities for additional cycles. Summing up the capacities up to the exhaustion point, the total of 6,208 mmol Zn (or 406 mg Zn) was removed per gram of zeolite, and total of 43,99 l zinc solution was treated on the same zeolite bed. These results confirmed column method more effective in treatment of a large volume of wastewater with lower initial zinc concentration compared to the batch method, and impose zeolite as a "roca magica".
