[ 1 ] - Removal of direct blue 129 from aqueous medium using surfactant-modified zeolite: a neural network modeling
Background: Conserving water for human survival and providing future security are important issues that need to be addressed. Methods: In this study, a zeolite modified with hexadecyl trimethyl ammonium bromide (HDTMA-Br), a cationic surfactant, and its application in removing direct blue 129 (DB129) was examined. Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy...
[ 2 ] - Removal of acid red 88 from wastewater by adsorption on agrobased waste material. A case study of Iranian golden Sesamum indicum hull
Background: Colors are very useful in different industries such as textile and leather but when they enter water, can cause many biological and environmental problems. In the present research, a waste agricultural material which is freely available is employed to analyze its efficiency for removing acid dye from contaminated wastewaters. Methods: In this study, batch adsorption experiments wer...
[ 3 ] - بازشناخت فناوری مصنوعات چرمی متعلق به دوره هخامنشی، مکشوفه از معدن نمک چهرآباد زنجان
Organic materials, due to their vulnerable structure, are considered as rare archeological materials. Therefore, the number of research and literature about these materials is limited. In this project, four leather artifacts found in Chehrabad Salt Mine of Zanjan belonging to Achaemenid period have been studied in three sections: first, identifying the type of animal whose skin has been used in...
[ 4 ] - بررسی کارایی شبکه عصبی مصنوعی در مدل‌سازی فرایند حذف مالاشیت سبز با استفاده از پسماند چای و بررسی ایزوترم
آلودگی آب یکی از مشکلات مهم جوامع امروزی است و همزمان با پیشرفت جوامع بشری، این مشکل نیز افزایش می‌یابد. یکی از مهم‌ترین آلاینده‌ها، وجود رنگ در نمونه‌های آبی است. جذب سطحی یکی از موثرترین فرایندها برای حذف این دسته از آلاینده‌ها است. در این پژوهش به بررسی فرایند و شرایط بهینه حذف رنگ مالاشیت سبز از محلول‌های آبی توسط پسماند چای عطری دوغزال پرداخته شد. برای دستیابی به شرایط بهینه حذف آل...
