HYDROCHEMISTRY OF THE TYRMA RIVER
Regional problems, 2021 The spatial-temporal dynamics of the dissolved substances content in the Tyrma River water and in its tributaries have been studied by the author. It was found great differences in the values of mineralization and concentrations of HCO3-, Ca2+, Mg2+ and Fe, due to natural conditions of the territory.

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 ...

Bio‐mediated cementation of supratidal beach sediments associated with groundwater springs
Sedimentology, EarlyView.ABSTRACT The formation of beachrock, sensu stricto, via carbonate precipitation in the intertidal zone is widespread throughout the tropics and subtropics. While cementation of supratidal beach sediments has also been noted in several locations, it has received much less attention.

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 ...
