Magnesium hydroxide precipitation ph
WebSince the optimal pH for precipitation depends both on the metal to be removed and on the counter ion used (hydroxide, carbonate, or sulfide), the best treatment procedure must be determined on a case- by-case basis. Metal solubility data are available in Benefield and Morgan, 1990, as well as in many other sources.
