ammonium sulphate precipitation using gypsum

fixation, this desulfurized gypsum is reacted with ammonia under a flow of carbon dioxide or with ammonium carbonate ((NH4)2CO3) obtained from the reaction between carbon dioxide and ammonia, producing ammonium sulfate ((NH4)2SO4) and the calcite forms of CaCO3 as the main products [20].

    Mar 29, 2021 1. Introduction. Sulfate attack is a process of chemical deterioration that occurs between the hydrated compounds of cement (alumina and calcium hydroxide) and the sulfate ions (SO 4-) bound to different cations such as Ca +, Mg +, NH 4-, Na +.Each type of sulfate acts by different mechanisms and may cause several problems related to material durability , , , .

    Step 2 -- Metal Hydroxide Precipitation. Wastewater with an initial sulfate concentration below 8000 mg/L, or which has already been treated using gypsum precipitation, is adjusted to a pH of 10.5 with hydrated lime. This removes metals as hydroxides and precipitates more gypsum, so approximately 2000 mg/L of sulfate remains in solution. As ...

    May 07, 2018 A method using the reaction of aqueous suspension of gypsum with ammonium carbonate solution with the following determination of the unreacted ammonium carbonate was developed. It was found out that the reactivity of the FGD gypsum from different sources is high and it is slightly correlated with the BET-specific surface (Danielik et al. 2016 ).

    Protein Precipitation Using Ammonium Sulfate

    Use analytical grade as lower grade material is often contaminated with heavy metals. Addition of ammonium sulfate acidifies the solution so use at least a 50 mM HEPES or Tris buffer etc., 5mM EDTA can also be included. Add solid ammonium sulfate slowly with gentle stirring; allow to dissolve before adding more solid, try to prevent foaming.
