"An efficient microwave assisted synthesis of halosubstituted chalcones by the condensation of halosubstituted ketones and substituted aldehydes. These reactions were found to economically cheap in comparison with classical synthesis."

Substituted benzyloxyphenyl chalcones 1a-j on reaction with hydrazine hydrate 2 and glacial acetic acid 3 in 2-methoxyethanol as reaction medium give novel substituted N-acetylpyrazolines 4a-j. Newly obtained N-acetyl pyrazolines characterized on the basis of IR, 1H-NMR, GC-MS and elemental analysis.

Studies about herbal products are increasing every day due to their rich biochemical content. Elaeagnus angustofolia is one of the best known plant species to have a strong biochemical substance spectrum. This work was performed to identify the some biochemical content of Eleagnus angustofolia. In this study, vitamins A, E, and C, total sugar content, inverted sugar content, cellulose content, amount of total protein, and fatty acid properties were studied. Our investigations revealed that Elaeagnus angustifolia has a strong content.

Decolourisation of wastewater, particularly from textile industries, is one of the major environmental concerns these days. Current methods for removing dyes from wastewater are costly and cannot effectively be used to treat wide range of such wastewater. This work describes the use of commercial available granular activated carbon (GAC) as an efficient adsorbent material for dyes removal. Aqueous solutions of various basic dye Methylene Blue (MB) and azo-dye Tartrazine with concentrations 5-20 mg l–1 and 10-100 mg l–1, respectively, were shaken with certain amount of GAC to determine the adsorption capacity and removal efficiencies. The effects of adsorbent dose, initial pH, initial dye concentration, agitation speed and contact time on dyes removal efficiencies have been studied. Maximum dye concentration was removed from the solution within 60-90 min after the beginning of every experiment. Adsorption parameters were found to fit well into Langmuir and Freundlich adsorption isotherms models with correlation coefficient (R2 > 0.99) in the concentration range of MB and TZ studied.
