Hettich EBA 20 Used in Organo-Bentonite Preparation for Methylene Blue Removal from Aqueous Effluent

Hettich EBA 20 Used in Organo-Bentonite Preparation for Methylene Blue Removal from Aqueous Effluent

Hettich’s EBA 20 Centrifuge played a major role in the study of Rarasaponins use for Organo-bentonite preparations, the subject of an article from the sciencedirect.com archives.

In this study, methylene blue was purchased as analytical-laboratory grade. Rarasaponin was obtained from the dried fruits of wild, tall tree Sapindus rarak DC, which originates in South East Asia. The rarasaponin extraction was achieved by crushing the Sapindus rarak DC’s dried fruits, Twenty grams of the Sapindus rarak DC powder was added to 200 mL of distilled water. The mixture was then heated, and the extract was separated from the solid using the Hettich EBA 20 Centrifuge for 10 minutes at 4000 rpm.

Dyes are usually produced by synthetic processes, generally characterized by complex aromatic molecular structure. The presence of these Dyes in aqueous effluent like in a river or stream is conspicuous, because dyes are often colored and highly visible. The dispersion of dyes into the aqueous effluent can endanger aquatic ecologies because of their often toxic characteristic. To treat wastewater contaminated with dyes with activated carbon is very expensive, the study employed rarasaponin, a natural surfactant extracted from wild plant Sapindus rarak DC. The substance was used as a modifying agent for the preparation of organo-bentonite, which is a low cost method used to remove the dyes.

The EBA 20 is not just limited to blood and urine applications. This clinical benchtop centrifuge is highly flexible, able to separate components of samples for diverse scientific applications. The analysis of rarasaponin and its interaction with other components was made possible with the Hettich EBA 20 Centrifuge. The model’s built-in, multi-functional 8-place angled rotor makes it very compact—occupying very minimal bench space. The EBA 20’s Safety-Lock™ Lid ensured sample security and optimal performance and the Run-Silent™ feature greatly minimizes distractions in the laboratory environment.
