Assessment of Water Quality Values in Porur Lake Chennai, Hussain Sagar Hyderabad and Vihar Lake Mumbai, India
Lake water is a source of drinking and domestic use water for rural and urban population of India. The main goal of the present study was to assess drinking water quality of various lakes i.e . Porur… Expand
Spectral and magnetic studies on manganese(II), cobalt(II) and nickel(II) complexes with Schiff bases.
Various physico-chemical techniques suggest an octahedral geometry for all the complexes. Expand
Coordination Modes of a Schiff Base Pentadentate Derivative of 4-Aminoantipyrine with Cobalt(II), Nickel(II) and Copper(II) Metal Ions: Synthesis, Spectroscopic and Antimicrobial Studies
The covalency factor (β) and orbital reduction factor (k) suggest the covalent nature of the complexes and the ligand and its complexes have been screened for their antifungal and antibacterial activities against three fungi and two bacteria. Expand
EPR, mass, IR, electronic, and magnetic studies on copper(II) complexes of semicarbazones and thiosemicarbazones.
