Abstract

For environmental applications, the production of inexpensive but superior adsorbents is essential. The Taguchi method was applied as an experimental design in this paper to determine the optimum conditions for the removal of crystal violet dye using pistachio shell powder in batch experiments. The effects of pH (3–9), initial dye concentration (2–10 mg·L-1 ), contact time (30–360 mins) and adsorbent dose (0.25–4 g·L-1 ) were studied using an L16 orthogonal array in order to achieve the maximum dye removal. For a "the-larger-thebetter" response, the percent dye removal was transformed into an accurate S/N ratio. In the studied range for various parameters, the optimal condition was found to be pH = 6, initial dye concentration=10 mg·L-1 , contact time=360 mins and adsorbent dose = 4 g·L-1 . Under the optimum conditions, dye removal percentage was obtained to be 93.6±0.1%. The analysis of variance results indicate that percentage contribution of control factor in descending order is adsorbent dose (33.17%) > initial dye concentration (27.43%) > pH (22.89%) > contact time (16.52%).

Özet

Çevresel uygulamalar için, ucuz ancak üstün adsorbanların üretimi önemlidir. Taguchi yöntemi, kesik deneylerde fıstık kabuğu tozu kullanılarak kristal viyole boyasının giderilmesi için optimum koşulları belirlemek için bu makalede deneysel bir tasarım olarak uygulanmıştır. PH (3–9), başlangıç boya konsantrasyonu (2–10 mg·L-1 ), temas süresi (30–360 dakika) ve adsorban dozunun (0.25–4 g·L-1 ) etkileri bir L16 ortogonal dizi kullanılarak maksimum boya giderimini sağlamak için çalışılmıştır. Bir "daha büyük-daha iyi" yanıtı için, boya çıkarma yüzdesi, doğru bir S/N oranına dönüştürülmüştür. Çeşitli parametreler için incelenen aralıkta optimum koşul; pH = 6, başlangıç boya konsantrasyonu = 10 mg·L-1 , temas süresi = 360 dakika ve adsorban dozu = 4 g·L-1 olarak bulunmuştur. Optimum koşullar altında boya çıkarma yüzdesi % 93.6 ± 0.1 olarak elde edilmiştir. Varyans sonuçlarının analizi, kontrol faktörünün katkı yüzdelerinin azalan sırada adsorban dozu (% 33.17) > başlangıç boya konsantrasyonu (% 27.43) > pH (% 22.89) > temas süresi (% 16.52) olduğunu göstermektedir.
