Heavy Metal Scavengers

Heavy Metal Scavengers

Low ppm level impurities removal from reaction mass

RESORB removes low ppm level impurities using Functionalised materials to improve product quality. Process and waste streams contain low concentrations (ppm) of metals, which leak into the system through raw materials or water. These metals are sometimes of value or interfere with the processes. RESORB uses such functional adsorbing molecules to remove impurities

There is a wide range of scavenging materials, particularly selective with their affinity for Pd(II), S n, Pb, Pt, Cu, Rh, Ru, Ag and Hg.

Processes in API pharmaceuticals, Biotechnology, Natural extracts, Specialty chemicals, mining, refineries, and electronics use these for metal purification, recovery and recycling.

In chemical synthesis research, development and manufacturing, RESORB solutions enhance and maintain product quality and optimise pharmaceutical production. RESORB technology recovers precious metals from liquid streams in industry. The low ppm level losses are immediately obvious visible.

Operation

The trial is conducted based on the impurity type, and then based on the selectivity, the RESORB functional group is chosen. The data then helps to scale up the system. Adsorption happens in counter-current columns—sizing is based on flow rates and ppm level of the impurity.
