Dynamic dissolution of halite rock during flow of diluted .

[3] The dissolution rate of halite was determined by Wagner from the weight loss of thin plates of halite rock suspended in water to be 5.3 × 10 −2 ± 25% mol/m 2 s. Alkattan et al. [1997] examined dissolution rate as a function of temperature, halite saturation degree, disk rotation speed, and concentrations of aqueous trace metals, and was found to range between ∼1 × 10 −1 and ∼9 × 10 −3 mol/m 2 s.

Halite is a common mineral found in sediment basin. However there is no good method to accurately measure the boron content in halite, which is mainly because Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) and Inductively Coupled Plasma Mass Spectrometer (ICP-MS) are limited by the high salt matrix interference and the instrument detection limit.
