Chromium has long been recognized as a toxic, mutagenic and carcinogenic metal. It is toxic to microorganism, plants, animals and humans. Chromium exists in environment in two stable forms CrVI and CrIII. CrIII is less toxic and insoluble, while CrVI is extremely toxic and highly soluble. Chromium is used in many industrial applications, but it poses a threat to local environment.

After the sample is dried, it is ready for magnetic separation. The magnetic separation process is necessary in order to rid the sample of any metals already within the original sample. Furthermore, metals also react and destroy the heavy liquids by producing a precipitate that is difficult to filter.
