Investigation of Cyanide, Arsenate, Phosphine and Nitrate Molecules in Samples of Water from Different Areas Using Raman Spectroscopy

Abstract

Water pollution is one of the biggest problems. This problem has become more and more dangerous as a result of harmful human activities. Increasing numbers of factories, use of fertilizers and pesticides to improve the quality and ripening of crops and also the random mining of minerals are responsible for rising water pollution. Cyanide, Arsenate Phosphine and Nitrates are very dangerous water pollutants and harmful chemical substances having adverse effect on humans, soil and animals. They are responsible for causing many dangerous diseases in humans. This study aims to investigate and determine the presence of these pollutants in water samples collected from northern Sudan. To examine water samples, a Horiba Lab RAM 3D Raman spectrometer was deployed. The findings showed that the samples include various amounts of harmful compounds such cyanide, nitrate, arsenate, and phosphine, which can cause fatal disorders in humans.
