Using the HClO4–H2O2 System for Efficient Platinum Leaching: Optimal Conditions and Kinetics

ChemPlusChem, EarlyView.
GA: The platinum leaching using HClO4 and H2O2 is studied. For each HClO4 concentration, an H2O2/HClO4 = 2.5 ratio optimizes the kinetics. The best operating conditions are ≈70 °C, [HClO4] 3 m, and [H2O2] 7.2 m. The leaching process is governed by diffusion in the boundary layer and chemical reaction. In this new extraction process, Cl2(g) is generated

Contributions of arid climate and hydrothermal fluid flow on sedimentation in saline‐alkaline lakes: Insight from the Ibar intramontane basin (Southern Serbia)

The Depositional Record, EarlyView.
The article demonstrates that brine was central for the supply of Ca and B to the studied saline lake. The ion transport occurred probably by thermal springs, while contributions from surface waters cannot be excluded. However, the saturation and syndepositional precipitation of Ca borates were initiated by an arid climate through evaporation, while ...
