Calcareous Soil as a Promising Adsorbent to Remove Fluoride from Aqueous Solution: Equilibrium, Kinetic and Thermodynamic Study
Abstract: Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 In this work, the feasibility of employing calcareous soil to remove fluoride ions from its aqueous solutions was investigated under batch mode. The influence of solution pH, sorbent dose, initial fluoride concentration, contact time, stirring rate and temperature on the removal process were investigated. The equilibrium adsorption data were analyzed using Langmuir, Freundlich and Temkin isotherm models. The kinetics of fluoride …

Copper (II) catalyzed oxidation of Hydrazine hydrate by Potassium ferricyanide
Abstract: The kinetics of Cu(II) catalysed oxidation of hydrazine by hexacyanoferrate(III) is studied in acid medium. The stoichiometry of the reaction is 1:1. The first order condition is [N2H5]>[Fe(CN)63- ] is maintained. The order of the reaction is unity with respect to Fe(CN)63-, fractional orders with respect to hydrazine and copper. The reaction is independent of variation of sulphuric acid and ionic strength. A suitable mechanism is proposed for the reaction. …

Process Parameters Optimization for Ammonia Decomposition up to 99% in Coke Oven Plants
Abstract: Catalytic ammonia decomposition is carried out in the byproduct-plant of Coke Oven-3. This process is picking up due to its ability to decompose the ammonia recovered from coke oven gas. Because of the corrosive nature of ammonia, its removal is a necessity in coke oven byproduct plants. The process begins with the ammonia vapors coming from the ammonia distillation column. The vapors from the distillation unit flow into a refractory-lined …
