[ 1 ] - Water Pollutants Adsorption through an Enhanced Activated Carbon Derived from Agriculture Waste
Background & Aims of the Study: A high nitrate and arsenic concentration in water resources represent a potential risk to the environment and public health. The present work improved a chemo-physically modified activated carbon derived from walnut shells as an adsorbent to improve nitrate and arsenic removal ability from water. Materials & ...
[ 2 ] - بررسی کارایی نانوکامپوزیت عاملدارشده PAMAM-GO در حذف نیترات از محیط‌های آبی
به دلیل حلالیت بسیار زیاد نیترات در آب، روش‌های متداول تصفیه قادر به حذف آن نیستند. این پژوهش با هدف تعیین کارایی نانوکامپوزیت عاملدار شده PAMAM-Go به‌منظور حذف نیترات از محیط‌های آبی در مقیاس آزمایشگاهی و به‌صورت پایلوت و برای اولین بار در ایران و جهان انجام شد. در این پژوهش سنتز گرافن اکساید به‌روش اصلاح شده هومر صورت...
[ 3 ] - An overview on PCBs in the environment, their health effects, identifying and removal methodsl methods
Introduction: PCBs are chemical resistant and biodegradable compounds which can have harmful effects on human health and the environment. These compounds are used in thermal, hydraulic, lubricating, pesticides, cosmetics, paint and paint products, adhesives, plastics, carbonless paper and electrical industries such as capacitors, transformer oils, disconnectors and fluorescent lamps. In the pre...
[ 4 ] - Investigation of concentration polarization in a cross-flow nanofiltration membrane: Experiment and CFD modelling
Numerous researches have been investigated on the mass transfer phenomena and hydrodynamics for the fluid in the vicinity of the membrane surface by the mathematical modelling and simulation. Due to complexities involved in solving transport phenomena within membranes, the application of CFD simulation study for determining the concentration polarization (CP) profile in the membrane channel is ...
