An Investigation of Cu2+ Removal by Using Different Types of Modified Starch

Abstract

In this study, Cu2+ removal from the aqueous solution using different types of starch was examined by the batch method. The potato starch and corn starch which were modified in different ways were examined to determine the percent removal values of Cu2+ by various trials. The optimum conditions of the experimental procedure were investigated from 10 to 50 mg L-1 as beginning concentration, 4 to 6 as pH, with 5-30 min. as shaking time. 0.15 g modified starch was added 50 mL study solution at room temperature during all different studies. The experimental results offered that thanks to the starch modification with water as an adsorbent, the percent removal values of potato starch 89.58% and corn starch 74.07% were found. Concentration, shaking time, and pH were detected with the optimum values as 20 mg L-1, 20 min, and 6 respectively. Moreover, the obtained results were also evaluated according to the Freundlich adsorption isotherm and observed to be compatible with this curve.

Modifie Edilmiş Farklı Nişasta Türleri Kullanılarak Cu2+ Geri Kazanımının İncelenmesi

Öz

Bu çalışmada, farklı nişasta türleri kullanılarak sulu çözeltiden Cu2+ katyonlarının geri kazanımı batch yöntemi ile araştırıldı. Farklı prosedürlerle modifiye edilmiş patates nişastası ve mısır nişastası kullanılarak çeşitli denemeler yapıldı ve Cu2+’nin geri kazanım yüzdeleri incelendi. Deneysel çalışmaların optimum parametrelerini bulabilmek amacıyla; başlangıç konsantrasyonu olarak 10 ila 50 mg L-1, pH olarak 4 ila 6 değerleri, çalkalama süresi olarak 5-30 dakika kullanılarak çalışmalar yapıldı. 0,15 g modifiye nişasta, 50 mL çalışma çözeltisine oda sıcaklığında ilave edildi. Nişasta modifikasyonunun su ile yapıldığı deneysel sonuçlara göre, adsorban olarak modifie edilmiş patates nişastası kullanıldığında %89,58, mısır nişastası kullanıldığında %74,07 olarak geri kazanım değerleri bulundu. Konsantrasyon, çalkalama süresi ve pH sırasıyla 20 mg L-1, 20 dakika ve 6 olarak optimum değerler tespit edildi. Ayrıca elde edilen sonuçlar, Freundlich adsorpsiyon izoterm eğrisine göre de değerlendirildi ve bu eğri ile uyumlu olduğu gözlemlendi.
