Chemical Degradation of Dieldrin using Ferric Sulfide and Iron Powder
The chemical degradation of dieldrin in ferric sulfide and iron powder aqueous suspension was investigated in laboratory batch type experiments. To identify the reaction mechanism, reduced copper was used as reductant. More than 90% of dieldrin was degraded using both reaction systems after 29 days. Initial degradation rate of the pesticide using ferric sulfide was superior to that using iron p...
متن کاملReductive dechlorination of p-chlorophenol by nanoscale iron.
OBJECTIVE To investigate reductive dechlorination of 4-chlorophenol (4-CP) by nanoscale Fe0 under different conditions. METHODS Nanoscale Fe0 was synthesized by using reductive method. 4-CP and its intermediate products were analyzed by HPLC. Chlorine ion was quantified with DX-100 ion chromatograph. Nano-iron particles were observed under a FEI Quanta 200 FEG environmental scanning electron ...
متن کاملDegradation of carbon tetrachloride in the presence of zero-valent iron.
Efforts to achieve the decomposition of carbon tetrachloride through anaerobic and aerobic bioremediation and chemical transformation have met with limited success because of the conditions required and the formation of hazardous intermediates. Recently, particles of zero-valent iron (ZVI) have been used with limited success for in situ remediation of carbon tetrachloride. We studied a modified...
متن کاملمدل سازی فرآیند حذف پرکلرواتیلن از آب بوسیله مانع واکنش دهنده نفوذ پذیر با بستر آهن صفر ظرفیتی
Background and objectives: Perchloroethylene (PCE) is categorized as contaminant of concern because of its adverse health effects and persistence in drinking water resources. Permeable reactive barrier with zero valent iron (ZVI-PRB) is a passive zone in which chlorinated ethenes are degraded in situ through the chemical reduction mechanism. The objective of the present investigation was optimi...
متن کاملGroundwater Remediation Strategy Using Global Optimization Algorithms
The remediation of groundwater contamination by pumping and injection is generally a long-term and costly strategy. Aquifer cleanup time is a highly nonlinear and nonconvex function of pumping rates. The cleanup objective often involves minimizing or constraining the cleanup time or cleanup cost. Linear programming and nonlinear optimization cannot guarantee the global solution. In this study, ...
