Arsenate coprecipitated with hydrous ferric oxide (HFO) was stabilized against dissolution during transformation of HFO to more crystalline iron (hydr)oxides. The rate of arsenate stabilization approximately coincided with the rate of HFO transformation at pH 6 and 40 °C. Comparison of extraction data and X-ray diffraction results confirmed that hematite and goethite were the primary ...

Reverse osmosis - Wikipedia
Reverse osmosis - Wikipedia

Reverse osmosis, (RO) is a water purification ,process, that uses a partially permeable membrane to separate ions, unwanted molecules and larger particles from drinking water. In ,reverse osmosis,, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter.

Concretely, (a) discrepancies in time-dependent viscosity curves are usually reported, that can be due to variable competition between shear-induced breakdown and by-hydration build-up of structure when the design of hysteresis loops is modified; (b) the rheological results depend on the mixing and handling protocol, probably due to the decrease of the yield stress with vigorous mixing; (c) slippage of pastes …
