Study on Organic Pollutant Sorption Used the Hettich EBA 20 Tabletop Centrifuge

Scientists employed the Hettich EBA 20 tabletop centrifuge in the study entitled “Comparative Studies Concerning the Behavior of Organic Pollutants in Iasi Area Soil.” Researchers aimed to compare the sorption behavior of two organic pollutants (dyes) Acid Orange 7 and Erythrosine B in soil.

The study begins by noting that “contamination of soil and groundwater by synthetic organic chemicals (e.g. dyes)” is becoming a growing concern. To test the sorption rates of the dyes, researchers first collected and classified local soil samples. Sorption experiments were then conducted in batches, and carried out for a 24-hour duration to achieve equilibrium.

After sorption, researchers centrifuged the sorbent for 20 minutes at 6,000 using the Hettich EBA 20 to separate the dye solutions. Data was collected and analyzed to construct a comprehensive report of influential sorption factors.

Researchers reported that major factors affecting sorption rates of Acid Orange 7 and Erythrosine B onto soil include initial dye concentration, soil amount, and contact time.

Hettich’s comprehensive line of centrifuges enables scientists to conduct important testing and research, such as this study on the sorption of organic pollutants. The Hettich EBA 20 is a compact, quiet, safe and reliable centrifuge that is suitable for clinical testing and research in many fields.
