Notes on the Gypsum Requirement (GR) of Soil

ADVERTISEMENTS: This article provides a notes on the Gypsum Requirement (GR) of soil. The main principle for the reclamation of sodic or alkali soils is to replace exchangeable Na by another ion calcium (Ca2+). Of all calcium compounds, gypsum (CaSO4.2H2O) is considered the best and cheapest for the reclamation purpose. Calcium (Ca2+) solubilized from gypsum

Calcium sulfate HydroLand

the dihydrate form (dihydrate), CaSO4 · 2H2O (M = 172.17 g · mol1), is known as gypsum Notes: heating the gypsum between 100 °C and 150 °C., partially dehydrates the mineral by driving about 75% of water contained in its chemical structure. The temperature and time required depends on the partial pressure of water.

What is CaSO4 Answers

Plaster of Paris is made from Gypsum CaSO4ܨH2O. Note that it has two molecules of water (H2O) in its crystal structure. If you heat Gypsum then waster is released thus 2 CaSO4ܨH2O → 2 CaSO4

Uptake and speciation of uranium in synthetic gypsum

In this study, synthesis experiments suggest an apparent pH control on the uptake of uranium in gypsum at ambient conditions: increase in U from 16 μg/g at pH = 6.5 to 339 μg/g at pH = 9.5. Uranium L3edge synchrotron Xray absorption spectroscopic analyses of synthetic gypsum show that uranyl (UO2)2+ at the Ca site is the dominant species.
