This study provides an electrocoagulation process for the removal of copper from water using mild steel and stainless steel as anode and cathode, respectively. The effect of different operating parameters and coexisting ions on the removal efficiency of copperwas investigated. The results showed that the optimum removal efficiency of 97.8% was achieved at a current density of 0.02 A/dm2 and a p...

The removal of tributyltin (TBT) from artificial seawater using nZnO, activated carbon and nZnO/activated carbon composite was systematically studied. The equilibrium and kinetics of adsorption were investigated in a batch adsorption system. Equilibrium adsorption data were analyzed using Langmuir, Freundlich, Temkin and Dubinin-Radushkevich (D-R) isotherm models. Pseudo first- and second-order...

In addition to the unique cover $M^+$ of variety modular lattices, we also deal with those twenty-three known covers that can be extracted from literature. For and for each these varieties covering it, determine what pair formed by number atoms coatoms a three-generated lattice belonging in question be. Furthermore, $W$ lattices is obtained forming join some mentioned above, is, $2^{23}$ possib...

An experimental study has been conducted on the adsorption of Direct red-28 dye using activated carbon prepared from Punica granatum (Pomegranate rind) by chemical activation with sulphuric acid. BET surface area of the activated carbon was determined as 1075.6 m.g and SEM observations showed the amorphous nature of the carbon. Adsorption kinetics, equilibrium and thermodynamics were investigat...

The series of batch laboratory experiment were carried out by using Acid Activated Ipomoea Carnea (AAIC) for the removal of copper (II) ions from aqueous solution by the adsorption process. The investigation was carried out by studying the influence of initial pH, contact time, adsorbent dosage and initial concentration of copper. All batch experiment was carried out of constant temperature usi...

We present CS(J=2-1) interferometric observations obtained with the Nobeyama Millimeter Array (NMA) toward a protostar (GH2O092.67 + 03.07) in the Cygnus OB7 giant molecular cloud (distance=800 pc). The data clearly indicate the presence of a compact (size ' 8 103AU) and young outflow with dynamical time scale ' 3500 year. The outflow is surrounded by a massive gas condensation. The analysis of...
