Abstract:

In this work is presented the physical-chemical characterization of Tekirghiol sapropelic mud (dry matter, humidity, volatile substances, total mineral substances) and also the minor elements existing in liquid phase and solid phase. The mineral contained analyses were performed with an atomic absorption spectrophotometer GBC AVANTA (air/acetylene flame) in order to determine the concentrations of heavy metals. Light metals were analysed using an atomic absorption spectrophotometer (ATI UNICAM SOLAAR 939). For the determination of pesticides in the sapropelic mud, a gas chromatograph Varian, coupled with electron capture detection ECD and a capillary chromatograph column SP5 was used. The sapropelic mud from Tekirghiol is high hydrated (71.16 %) and rich in mineral substances (20.96 %).

Keywords:

sapropelic mud, therapeutically factor, microelements, light metals, organochlorinated pesticides, organophosphoric pesticides.
