  • October Tech Tip: Metals Sorption and pH

    At the ambient pH of most aquifers many dissolved metals (Ag, Ba, Cd, Cr, Cu, Fe, Li, Mn, Ni, Pb, Zn) are present as positively charged ions (cations). Transport of these dissolved cations is often controlled by sorption to negatively charged surfaces including sediment iron oxides (e.g., goethite, ferrihydrite, and hematite). At low pH, iron oxides take on a positive charge and sorption of metal ...

  • VOCs – why speciate?

    The Quantitech stands (Nos. 44 & 51) at AQE 2015 in Telford, the air quality and emissions show, will feature three different technologies for measuring individual organic compounds. This is extremely important because VOCs mostly exist in a mixture of more than one organic compound, so measurements can be misleading unless the individual compounds are speciated. Firstly, AQE2015 will provide ...
