İçme Suyu Arıtma Çamuruna Çinkonun Adsorpsiyonu

Öz

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.

Adsorption of Zinc into Drinking Water Treatment Sludge

Öz

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.
