Abstract: Eco-friendly adsorbent has been reported as an alternative to the current expensive methods of removing of iron and malachite green (MG) dye from aqueous solution. Iron is also an essential constituent of human body which helps for better regulation of the body. Certain amount of Iron is required for both the male and female body to avoid Iron deficiency in the body, despites this Iron can be harmful for the human body if intake in larger amounts.The effects of different variables, adsorbent dosage, initial dye concentration, pH, contact time, temperature etc.Iron metal used for different purpose.

Abstract: Chemicals typically available in plants have the capability to reduce thorium and to create thorium nanoparticles. We report the preparation of thorium nanoparticles with sizes between 1μm to 100 nm from thorium nitrate using fruit extract collected from pineapples as reducing agents. The resulting nanoparticles were characterized by Scanning Electron Microscopy, Fourier Transform Infrared (FTIR), EDAX, Powder X-ray Diffractions (PXRD) and Anti-cancer activity

Abstract: A novel Cu(II) complex of 2,4-thiozolidinedione(TLD) and benzoate ion was synthesized by using microwave irradiation. Microwave synthesis gives a high yield of the complex within a short time. The molecular formula and the probable geometry of the complex have been deduced from elemental analysis, molar conductance, UV-Vis, FT-IR, and EPR spectra. The molar conductance value indicates that the Cu(II) complex is a non-electrolyte. FT-IR spectra show that 2,4- thiazolidinedione and benzoate ion are coordinated to the metal ion in a monodentate way. The metal ligand covalancy of Cu(II) complex has been arrived at from EPR spectrum. The geometry of the complex is found to be tetragonally distorted octahedral. The antimicrobial activities of the ligands and their Cu(II) complex are studied against the five bacteria (staphylococcus aureus, serratia, salmonella typhi, chromobacterium violaceum and burkolderia) and also two fungi (C.albicance and Aspergillus Niger) at different concentrations by agar- well diffusion method. The complex shows enhanced activity against the bacteria and moderate activity against the fungi compared to the free ligands.

Key Words: Cu(II) complex, 2,4-thiozolidinedione benzoate ion, antimicrobial.

Abstract: Oxidation of organic compounds is quite important from synthetic and technological view points. Many of the industrially important organic compounds like aldehydes, ketones, acids, etc. can be produced by the oxidation of related substrate by the use of suitable oxidizing agents. The kinetics of the oxidation of 1-Phenylethanol (PE) by PS-Chromate has been followed by monitoring the constant in the absorbance of reaction intermediate. The reaction followed by zero order behavior, being zero order in each reactant. The rate of reaction constant with increase in weight of oxidant, concentration, temperature and dielectric constant of the solvent. A free radical scavenger affects the reaction rate. The stiochiometry has been found to be 1mol PE: 1mol of Chromate. Thermodynamic parameters evaluated are [Ea] = 85KJ mol-1, [ΔH#] =53 KJ mol-1, [ΔS#] = -70 JK mol-1, [ΔG#] =306KJ mol-1, and [A] =3.6 x 10-5s-1 results under pseudo zero order conditions are in agreement with the rate law. The object of the present study is the oxidation of aromatic secondary alcohol by ion exchange resin by Tulsion-421.

Abstract: In this review article attention is put towards the application of a common Indian medicinal plant, AloeVera that has been put into use since centuries for its therapeutic and curative properties. Aloe gel, which is found in the interior of the leaves, is being used for topical application for many skin ailments. The gel works by hydrating and protecting a topical wound until the body can repair itself. The bitter latex comesfrom a layer of cells just beneath the outer skin and has been reported to be beneficial in treatment of intestinal troubles. This sap is taken internally and soothes digestive complaints by acting as a purgative orlaxative. An Aloe Vera leaf contains more than 200 different constituents...........
