Effects of Hydrochloric and Acetic Acid Modification on the HTAB and K+ Adsorption Characteristics of Natural Zeolites

Öz:
In this study, the effects of hydrochloric acid (HCl) and acetic acid (HAc) modification on the hexadecyltrimethyl ammonium bromide (HTAB) and K+ adsorption characteristics of a natural zeolite wereinvestigated. Electrokinetic evaluations showed that the zeta potential values of acid-modifiedsamples were considerably more negative compared to natural zeolite. Additionally, the pHregulation behavior of the acid-modified samples was found to differ from the natural zeolite sampleand it was in agreement with the results of zeta potential measurements. It was clear that the acidmodification processes positively affected the surface properties and improved the cation exchangecapacity (CEC) of natural zeolite. The results for the adsorption studies showed that the adsorptiondensity of zeolite increased at elevated HTAB and K+ concentrations. Moreover, following the zeta andpH profile results, a considerable difference in the adsorption ability between natural and acidmodified zeolite samples is present in terms of HTAB and K+ adsorption characteristics. It isconcluded that acid modification can be used in the enhancement of the adsorption ability of zeolites.

Hidroklorik ve Asetik Asit Modifikasyonunun Doğal Zeolitlerin HTAB ve K+ Adsorpsiyon Karakteristikleri Üzerindeki Etkileri

Öz:
Bu çalışmada hidroklorik (HCl) ve asetik asit (HAc) modifikasyonunun doğal zeolitlerin HTAB ve K+ adsorpsiyon karakteristikleri üzerindeki etkileri araştırılmıştır. Yapılan elektrokinetik değerlendirmeler asitle modifiye edilmiş örneklerin zeta potansiyeli değerlerinin doğal zeolite kıyasla önemli derecede daha negatif olduğunu göstermiştir. Buna ek olarak, asitle modfiye edilmiş örneklerin pH davranışının zeta potansiyeli ölçümü sonuçları ile uyumlu bir şekilde doğal zeolit örneklerinden farklı olduğu bulunmuştur. Asit modifikasyonu işlemleri doğal zeolitlerin yüzey özelliklerini ve katyon değişim kapasitelerini olumlu olarak etkilemiştir. Adsorpsiyon çalışmalarının sonuçları zeolitin adsorpsiyon yoğunluğunun yüksek HTAB ve K+ konsantrasyonlarında arttığını göstermiştir. Ayrıca, zeta ve pH profili sonuçlarını takiben HTAB ve K+ adsorpsiyonu açısından doğal ve asitle modifiye edilmiş örnekler arasında adsorpsiyon yeteneği açısından kayda değer bir farklılık bulunduğu belirlenmiştir. Asit modifikasyonunun doğal zeolitlerin adsorpsiyon yeteneğinin geliştirilmesinde kullanılabileceği sonucuna varılmıştır.
