Background & Aims of the Study: Organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. The aim of this study was to evaluate the performance of H2O2 and H2O2/Fe0 Iron in removal of dye Acid Red 18 from aque...
Green Synthesis of Nano-Zero-Valent Copper for the D-Blue 60 Textile Dye Removal from Aqueous Medium
Abstract Green synthesis of zero-valent copper nanoparticles successfully performed using Ficus benjamina leaves. The novel adsorbent nano-zero-valent (FB-nZVCu) characterized by utilizing scanning electron microscopy (SEM) and Fourier transforms infrared spectroscopy (FT-IR). size these typically ranges from 16 to 18 nm. This investigated for removal D-blue 60 textile wastewater. impact differ...
Understanding the interactions between natural organic matter (NOM) and zero-valent iron nanoparticles (nano-Fe0) and magnetite nanoparticles (nano-Fe3O4) is essential for evaluating their performance in pollutant remediation, as well as determining their fate and transport in the environment. Batch experiments were performed to investigate the sorption/desorption behaviors of humic acid (HA) o...
زمینه و هدف: حضور باقیمانده آنتی بیوتیک ها در محیط زیست امروزه به عنوان یکی از نگرانی های جهانی مطرح شده است و لزوم کنترل تخلیه آنها نیز بعنوان امری اجتناب ناپذیر مطرح شده است. این تحقیق، با هدف بررسی کارایی فرآیند تلفیقی شبه فنتون (uv/h2o2/nzvi) جهت تجزیه آنتی بیوتیک تتراسایکلین از محیط های آبی صورت گرفت. مواد و روشها: این تحقیق یک مطالعه تجربی بود که در مقیاس آزمایشگاهی و در دمای محیط انجام گ...
