Abstract
Bu çalışmada, dokuma hazırlama aşamasında yaygın olarak kullanılan ticari noniyonik bir tekstil yüzeyaktif maddesinin (alkil polietilen glikol eter formülasyonunda) H2O2/UV-C ileri oksidasyon prosesi ile fotokimyasal arıtılabilirliği araştırılmıştır. Bu amaçla pH, H2O2 ve kirletici konsantrasyonu gibi farklı proses değişkenlerinin arıtma verimindeki etkileri ve kinetikler değerlendirildi ve fotokimyasal arıtım için optimum reaksiyon koşulları belirlendi. Ayrıca, incelenen kirletici için en uygun arıtım tipi ve sırasını önermek amacıyla ham ve fotokimyasal olarak ön arıtılmış tekstil yüzeyaktif maddesinin biyolojik arıtılabilirliği çalışılmıştır.
In the present experimental study, the photochemical treatability of a commercial nonionic textile surfactant (a polyethylene glycol ether formulation) frequently used in the fabric preparation stage with the H2O2/UV-C advanced oxidation process was investigated. For this purpose, the effect of different process variables such as pH, H2O2 and pollutant concentration on the treatment efficiency and kinetics was evaluated and optimum reaction conditions of photochemical treatment were established. In addition, the biodegradability of untreated and photochemically pretreated textile surfactant was also studied to propose the most favorable treatment type and sequence for the investigated pollutant.
