Abstract

A new low-cost, locally available sorbent sumac (Rhus coriaria L.) leaves (SL) and resins prepared from tannic acid/ gelatin (TG) and tannin from sumac leaves/ gelatin (STG) were tested for its ability to remove Zn(II) ions from aqueous solutions. The biosorption studies carried out with single metal solutions. The removal of Zn(II) from aqueous solution increased with pH and sharply decreased when pH of solution was decreased. Batch isotherm of biosorption zinc ions was investigated. The Freundlich, Langmuir and Tempkin models can describe the adsorption equilibrium of Zn(II) on SL, TG resin and STG resin. The biosorption constants were found from the Freundlich, Langmuir and Tempkin isotherms at room temperature. It is found that the biosorption data of zinc on SL, TG resin and STG resin fitted the Freundlich, Langmuir and Tempkin adsorption models. This study investigated also thermal analysis of TG and STG resins. The TGA-DTG curves of all the resins were similar and showed three steps in a similar way to a phenolic resin. This means that each resin is well crosslinked

Özet

Yeni, ekonomik sumak (Rhus coriaria L.) yaprakları (SL) ve reçineler ki bunlar tannik asit/jelatin (TG) ve sumaktan elde edilen tannin/ jelatin (STG) sulu çözeltilerden Zn(II) iyonun uzaklaştırmak kullanılmıştır. Biosorpsiyon çalışmaları tek bir metal iyonu üzerinden gerçekleştirilmiştir. Çözeltiden Zn(II) iyonu uzaklaştırmada ortamın pH değeri arttığında biosorpsiyon artmış, pH düştüğünde keskin bir düşüş gözlenmiştir. Çinko biosorpsiyonu SL, TG reçinesi ve STG reçinesi için; Freundlich, Langmuir ve Tempkin izotermleri ile yorumlanmıştır. Çinlo biosorpsiyonunun SL, TG reçinesi ve STG reçinesi için Freundlich, Langmuir ve Tempkin izotermlerine uyduğu gözlemlenmiştir. Ayrıca bu çalışmada TG ve STG reçinelerinin ısısal özellikleri incelenmiştir. Bütün reçinelerin TGA-DTG eğrileri incelendiğinde fenolik reçineler gibi üç basamaklı olduğu gözlenmiştir. Bu da reçinelerin iyi ağ örgülü yapı gösterdiğini ispatlamaktadır
