Abstract

In this experimental study, lead removal from synthetic and industrial wastewaters was carried out by biosorption using the seed part of Capia pepper residual as a low cost biosorbent. There is no study in the literature on lead removal from real wastewaters with raw Capia pepper seeds. Although it is important to evaluate a residual material in the treatment process, the results to be obtained will shed light on future studies. The effects of initial pH, the dose of biosorbent, treatment duration, and initial lead concentration on treatment efficiency were examined to determine the most suitable treatment conditions for this biosorbent. Biosorbent was used without any pre-treatment. The optimum pH was found to be 5 for lead treatment studies. The maximum removal efficiency of 94.46% was obtained by using 5.4 g/L dry biomass (125-250 µm in size). The data of lead biosorption were found to be favorable to the pseudo-second order kinetic model. Also, the rate-limiting step was not only the intraparticle diffusion according to the Weber-Morris model. While the isotherm data fitted very well to the Langmuir isotherm model, the Freundlich and Temkin isotherm models were insufficient. The highest biosorption capacity for this biosorbent was found to be 29.67 mg/g at 25°C. In the studies carried out with storage battery industry wastewater, it was concluded that the maximum removal efficiency (71%) in real wastewater was lower than the efficiency obtained in synthetic wastewater due to the low lead concentration and complex structure of real industrial wastewater.

Özet

Bu deneysel çalışmada, düşük maliyetli bir biyosorbent olan kapya biberi artığının çekirdek kısmı kullanılarak sentetik ve endüstriyel atıksulardan biyosorpsiyon ile kurşun giderimi gerçekleştirilmiştir. Gerçek atıksulardan kurşun giderimi üzerine literatürde ham kapya biberi çekirdekleri ile yapılmış çalışma bulunmamaktadır. Artık bir materyalin arıtım prosesinde değerlendirilmesi önem taşımakla birlikte elde edilecek sonuçlar ileri ki çalışmalara da ışık tutacaktır. Bu biyosorbent için en uygun arıtım koşullarını belirlemek amacıyla başlangıç pH değerinin, biyosorbent dozunun, arıtma süresinin ve başlangıç kurşun derişiminin arıtım üzerine etkisi incelenmiştir. Biyosorbent herhangi bir ön arıtım uygulanmaksızın kullanılmıştır. Kurşun arıtım çalışmaları için en uygun pH değeri 5 olarak tespit edilmiştir. Maksimum giderim verimi olan %94,46 değeri, 5,4 g/L kuru biyosorbent (125-250 µm boyutunda) kullanılarak elde edilmiştir. Kurşun biyosorpsiyonu verilerinin yalancı-ikinci derece kinetik modeline uyduğu bulunmuştur. Aynı zamanda Weber-Morris modeline göre, hızı sınırlayan adım tek başına partikül içi difüzyon değildir. İzoterm verileri Langmuir izoterm modeline çok daha iyi uyum sağlarken, Freundlich ve Temkin izoterm modelleri yetersiz kalmıştır. Bu biyosorbent için en yüksek biyosorpsiyon kapasitesi 25°C’de 29,67 mg/g olarak bulunmuştur. Akü sanayi atıksuyu ile yürütülen çalışmalarda, gerçek endüstriyel atıksuyun sahip olduğu düşük kurşun derişimi ve kompleks yapısı nedeniyle, gerçek atıksudaki maksimum giderim veriminin (%71) sentetik atıksularda elde edilen verimden daha düşük çıktığı sonucuna varılmıştır.
