Water purification - Wikipedia

For highly acidic waters, forced draft degasifiers can be an effective way to raise the pH, by ,stripping, dissolved carbon dioxide from the water. Making the water alkaline helps coagulation and flocculation processes work effectively and also helps to minimize the risk of lead being dissolved from lead pipes and from lead solder in pipe fittings.

The process of ,palladium(II) chloride complex ion adsorption on activated carbon, was investigated. The influence of variable parameters such as the initial concentration of the Pd(II) complex (from 0.04 to 2.25 mmol·kg–1) and temperature (from 294 to 348 K) was determined. Experiments were conducted in the solution with pH equal to 0 and 1. It was found that the Freundlich adsorption ...
