Determination of Heavy Metals Concentrations from Waste Waters from
Rm.Vâlcea Chemical Platform to Establish the Pollution Level


Abstract:

Heavy metals are natural components of Earth’s crust.They cannot be degraded or destroyed. The impurification of water surfaces with havy metals has many times disastrous effects on environment. That’s why the determination of havy metals concentrations at levels of ppm or ppb is strictly necessary. Industrial, economical and demographic development generate huge amounts of wastes which have different chemical composition and variable content in toxic havy metals. A defective management of these wastes lead to environment pollution and then to its degradation. This paper presents a method of determination of these components and what are the toxic havy metals levels in waste waters from Rm.Valcea Chemical Platform in point „Olt Deversor”.The most toxical havy metals determinated were: Ni, Cr, Zn, Fe, Cu,. The concentration of these metals was determinated by atomic absortion spectrometry method (AAS) using an analyzer type A ANALYST 700. Keywords:water wastes, heavy metals, pollution, environment
