Abstract:The potential value and the problems associated with the usage of spentwash in Rampur District were studied and also their environmental impacts were discussed. The studies revealed that, though at higher doses (> 250 m 3 / ha) spentwash application is found detrimental to crop growth and soil fertility, its use at lower doses (125 m 3 /ha) remarkably improves germination, growth and yield of dryland crops. Further, it has been revealed that conjoint application of spentwash and organic amendments (farm yard manure, green leaf manure and bio-compost) is found suitable under dryland conditions. Large amounts of soluble salts have been found to be leached from calcareous and high pH sodic soils amended with spentwash. Notably, application of spentwash has resulted in leaching of high amounts of sodium from high pH sodic soils reflecting its potential in ameliorating these soils. However, exceptionally high loading of the leachate with organic and inorganic contaminants may pose potential risk for groundwater contamination.
Abstract:A systematic study has been carried out to explore the water quality index of ground water of various tehsils of Rampur district. Twenty five water samples from tube wells, open wells and hand pumps at various locations were collected and analyzed for pH, nitrate, turbidity, total dissolve solid, chlorides, total hardness, alkalinity and fluoride. In this study overall water quality of Rampur district is very poor and unsuitable for drinking purpose. Water quality of Bilaspur, Shahabad and Rampur city shows that water may not be used for drinking as well as domestic purpose. Present study recommends that the top priority should be given to water quality monitoring and indigenous technologies should be adopted to make water fit for drinking after treatment such as defluoridation, desalination.
The present work describes the synthesis and characterization of some six and nine coordinated complexes of trivalent lanthanide(III) with 4[N-(2´-hydroxy-1´-naphthalidene)amino]antipyrinethiosemicarbazone (HNAAPTS). All the complexes have the general composition LnX 3 .n(HNAAPTS) (X = NO 3 -, n = 1; X = NCS -or ClO 4 -, n = 2). The complexes were characterized through elemental analyses, molar mass, conductivity measurements, magnetic susceptibilities, and infrared and electronic spectra. Infrared spectra revealed that HNAAPTS acts as a neutral tridentate (N,N,S) donor. The coordination number in these complexes is either six or nine depending on the nature of the anionic ligand.
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.
