Abstract

Bu makalede bitkisel kaynaklı bir biyosürfektan olan Quillaja saponini ekstraktlarının alternatif, düşük maliyetli ve doğal sürfektan olarak koyun derilerinin yağ giderme işleminde kullanımı incelenmiştir. Pikle koyun derileri farklı oranlarda sapogenin içeren üç ticari Quillaja saponaria ürünüyle Q1 (Sigma, 26%), Q2 (AppliChem, 12%) ve Q3 (Carl Roth, 10%) işlenmiştir. Saponin kullanımına dayalı biyo-yağ giderme işleminin etkisi atık banyoların kimyasal oksijen ihtiyacı (KOİ), derilerin rengi ve taramalı elektron mikroskobuyla derilerin kesiti incelenerek belirlenmiştir. Q1, Q2 ve Q3’ün %3.75 sapogenin konsantrasyonuyla gerçekleştirilen yağ giderme işlemlerinde sırasıyla %82, %79 ve %78’e varan oranlarda yağ giderme etkinlikleri elde edilmiştir. Q1 saponini % 3.125 oranında kullanıldığında yağ giderme atık sularının KOİ değerleri %70 oranında azaltılmıştır. Sonuçlar biyosürfektanlar ile yağ gidermesi yapılmış derilerin düzgün boya dağılımı ve fiziksel yapı açısından geleneksel yöntemle işlenen derilere benzer özelliklere sahip olduğunu ve bu çalışmada geliştirilen, saponin kullanımına dayalı yağ giderme işleminin deri endüstrisi için uygulanabilir, gelecek vaat eden ve ekolojik bir alternatif olabileceğini göstermektedir

EVALUATION OF DEGREASING PROCESS WITH PLANT DERIVED BIOSURFACTANT FOR LEATHER MAKING: AN ECOLOGICAL APPROACH

Abstract

This paper describes the application of extracts of Quillaja bark saponin, a plant derived biosurfactant, as alternative low cost natural surfactants for the degreasing of sheep skins. Pickled sheep skins were treated using three commercial products of Quillaja saponaria saponins with different degrees of sapogenin content: Q1 (Sigma, 26%), Q2 (AppliChem, 12%) and Q3 (Carl Roth, 10%). The effect of saponin based biodegreasing was investigated in terms of chemical oxygen demand (COD) of residual floats, quantification of colour and scanning electron microscopic visualization of the biodegreased leathers. Degreasing efficiency levels up to 82%, 79% and 78% was attained with 3.75% sapogenin content of Q1, Q2 and Q3 respectively. COD values for degreasing effluents were reduced by 70%, with 3.125% offer of Q1 saponin. The results indicate that the properties of biodegreased leathers are comparable with those of conventionally processed leathers with respect to dye levelness and physical texture. This novel saponin based degreasing process can be a viable and promising ecological degreasing option for leather industry
