Abstract
In this study, the removal of zinc ion by use of wastewater sludge was aimed. By determining the optimum conditions in the study; The effects of parameters such as balance, pH, sorbent amount and metal concentration of the processes in different situations were investigated. In the adsorption of Zn+2 ions with drinking water treatment sludge, optimum initial pH was determined as 5.0, time to equilibrium was 60 minutes, sorbent dose was 0.3 g/L, and initial ion concentration was 25 mg/L. While sorbent amount was 0.1 g/L, removal efficiency was 73.2% and qe was 18.3 mg/g. It was calculated as 90.8%, 4.54 mg/g for 0.5 g/L sorbent and 92.4% and 2.31 mg/g for 1 g/L sorbent. At the Zn +2 5 mg/L concentration, the removal efficiency was 1.53% and qe was 92 mg/g. At 50 mg/L Zn+2 concentration, the removal efficiency was calculated as 70% and qe was calculated as 11.67 mg/g. In the study, it has been proven that drinking water treatment sludge can be used as a promising adsorbent for the removal of Zn+2 ions from the aqueous solution.
Özet
Bu çalışmada, Sivas içme suyu arıtma çamuru kullanılarak çinko (Zn+2) iyonunun giderimi amaçlanmıştır. Çalışmada optimum koşullar belirlenerek; proseslere ait denge, pH ve sorbent miktarı ve metal konsantrasyonu gibi parametrelerin farklı durumlarda etkileri incelenmiştir. Zn+2 iyonlarının içme suyu arıma çamuru ile adsorpsiyonunda, optimum başlangıç pH’sı 5.0, dengeye süresi 60 dk., sorbent dozu 0,3 g/L ve başlangıç iyon derişimi 25 mg/L olarak belirlendi. Sorbent miktarı 0,1 g/L iken giderim verimi %73,2 ve qe 18,3 mg/g olarak gerçekleşti. 0,5 g/L sorbent için % 90,8, 4,54 mg/g ve 1 g/L sorbent için %92,4 ve 2,31 mg/g olarak hesaplandı. Zn +2 5 mg/L konsantrasyonunda giderim verimi %1,53 ve qe 92 mg/g olarak gerçekleşti. 50 mg/L Zn+2 konsantrasyonunda ise giderim verimi %70 ve qe 11,67 mg/g olarak hesaplandı. Çalışmada içme suyu arıtma çamurunun sulu çözeltiden Zn+2 iyonlarının uzaklaştırılması için umut verici bir adsorbent olarak kullanılabileceği kanıtlanmıştır.
