Safe drinking water is the primary need of time most of the people depends upon groundwater sources that have problems of hardness, calcium, Nitrate, Phosphate, fluoride, D.O., B.O.D., COD and heavy metals copper and Zinc and excess of MPN count, Different samples has collected in pre and post monsoon seasons during 2008-09. Different parameters of water has been analyzed and evaluated to the suitability of drinking water for human consumption and public hygiene scenario and health impacts. Some of the parameters are observed within the prescribed limits of 15 : 10500 while others are beyond the limits of WHO and ISI.
The reactions of phenylphosphonic acid [(OH) 2 POC 6 H 5 ] (PPA) with a variety of ditopic pyrazoles Pz R1,R2 H (where R 1 = R 2 = H for 1, R 1 = R 2 = Me for 2, R 1 = Ph, R 2 = Me for 3 and R 1 = R 2 = iPr for 4) produce salts 1-4. Due to the presence of different substituents on pyrazole, each salt shows different structure. This study demonstrates that the presence of different substituents on the pyrazole moieties provides sufficient non-covalent interactions which are responsible for the different supramolecular structures adopted. Theoretical studies reveal that the proton affinity increases on the nitrogen having lone pair of electron with the increase of electron density on pyrazole ring but the orientation remains the same in both the solid and gaseous phase.
Reaction of benzene-1,3,5-tricarboxylic acid (H3BTC) with various 3,5-substituted pyrazoles resulted in different host guest assemblies. Theoretical calculations were used to calculate the interaction energy and their comparison with the experimental data obtained through thermogravimetric analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
