Hydrochemistry of the Parana River [PDF]
Limnology and Oceanography, 1976 Recent monthly data from the Paraná River show that its hydrochemistry is controlled by the nature of the rocks in the basin, with significant contributions from saline environments during low discharge. The discharge‐weighted mean dissolved salts concentration (79.8 mg liter‒1) allows a new calculation of 56.7 mg liter‒1 for the mean dissolved salts ...

Validation of hydrogeochemical databases for problems in deep geothermal energy
Geothermal Energy, 2018 Hydrogeochemical modelling has become an important tool for the exploration and optimisation of deep hydrogeothermal energy resources. However, well-established software and model concepts are often run outside of its temperature, pressure, and salinity ...

Production of redox-active-reactive filter material from charcoal
Next MaterialsThe surficial and textural features of a pyrogenic carbonaceous material (charcoal) was modulated with acidic Piranha solution (i.e., 1:3 30% H2O2 to H2SO4) to produce a redox-active adsorbent for the simultaneous adsorption and reduction of Cr(VI) in ...
