2015. Date stones (DS) were used as precursor for the preparation of activated carbon (DSAC) by chemical activation with sulphuric acid. The batch adsorption of Cr(VI) on DSAC were carried out at room temperature (25±2°C) and effects of various parameters such as pH solution, initial metal ion concentration, adsorbent dose and contact time were studied.

This distillery-grade activated stone carbon is great for stripping out all the undesirable components from your distillate. However, it can also strip the flavor out of whiskey, rum, or brandies, so it is not recommended for these finished products. Unlike a lot of our other carbon products, this needs to be rinsed prior to use.
