Removal of Heavy Metals from Industrial Waste Water Using the Laser Radiation
https://doi.org/10.18412/1816-0395-2015-5-26-30
Abstract
The results of investigation into the influence of laser radiation on heavy metal ions (Cu2+, Ni2+) in water medium. To reveal the effect of the laser radiation, model aqueous
solutions of copper(II) and nickel(II) with the content of copper of 0,25–1 mg/L and that of nickel of 0,5–5 mg/L were used. To irradiate the solutions, helium-neon
and argon gas-discharge lasers with various wavelengths were used. It is established that the intense deposition of metal ions is caused by the photochemical reduction,
two-photon photolysis of water, and synthesis of nanoparticles in liquid media, particularly by the formation of active particles under the effect of laser radiation and
formation of colloid metal clusters. The application of laser technologies in modern purification systems of industrial waste water based on physicochemical methods
will make it possible to broaden the range of heavy metals subjected to removal and increase in the purification efficiency of waste water.
