Spectrochemical Analysis of Lonar Lake Water and Sediment using dc-glow Discharge Technique

Abstract

The dc-glow discharge technique was employed to study the excitation mechanism of water (brine) and sediment of the Lonar crater. The elemental analysis of the crater water and sediment was carried out. The yield of Fe from the crater water was obtained by the dc glow discharge. The spectra of the Lonar water and sediment sample emitted during glow discharge are recorded using PMT and Monochromator. The various emission peaks in the region 400 to 480nm of the spectrum indicate the contamination of the different metals Fe, Ni and Ti in sediment sample. The percentage of Fe 1.946 % and of Ni 6.842 % is estimated gravimetrically from the sediment sample in the Lonar crater.
