Malahit yeşili boyar maddesinin çam kozalağı ile adsorpsiyonunun Taguchi metodu ile incelenmesi

Bu çalışmada Taguchi deney tasarımı kullanılarak Kars-Sarıkamış ormanlarından toplanan çam kozalakları ile malahit yeşilinin adsorpsiyonunun optimizasyonu çalışıldı. Adsorpsiyon üzerine etki edebilecek parametreler, temas süresi, başlangıç konsantrasyonu, başlangıç pH’ ı ve tane boyutu olarak seçildi. Optimum seviyeler sırasıyla temas süresi 240 dk, başlangıç konsantrasyonu 100 mg.L-1, pH 5 ve tane boyutu (-425+300) olarak belirlendi. Optimum şartlarda maksimum adsorplanan malahit yeşili miktarı 9,72 mg/g olarak bulunmuştur. Proses parametrelerinin etkisini görmek için ANOVA analizi yapıldı ve başlangıç konsantrasyonu, başlangıç pH’ı ve tane boyutunun etkin olduğu saptandı.

Investigation of adsorption of malachite green dye on pine cone using Taguchi method

In this study, optimization of adsorption of malachite green on pine cones collected from Kars-Sarıkamış forest was studied using Taguchi experimental design. Contact time,initial concentration, initial pH and particle size were selected as affecting adsorption parameters . Optimum levels for adsorption experiments were determined as contact time=240 min, initial concentration=100 mg L-1, pH=5, and particle size = (-425+300), respectively. At optimum levels, the amount of maximum adsorbed malachite green was found to be 9,72 mg/g. ANOVA analysis was performed to understand the effect of process parameters and initial concentration, initial pH and particle size were found to be effective.
