Procedure optimization of silicate rocks dissolution in open vessels for ICP-AES analysis.
(Editora Unesp, 1996-01-01)
The main variables found on procedure of the dissolution silicate rocks using acid dissolution in teflon open vessel for analysis of micro elements by ICP-AES has been determined. The results obtained for some samples ...

A discriminating dissolution method for glimepiride polymorphs
(Wiley-Blackwell, 2012-02-01)
Glimepiride, an oral antidiabetic drug, is practically insoluble in water and exists in two polymorphic forms, I and II, of which form II has higher solubility in water. Because the dissolution rate of drugs can depend on ...

Understanding the acid dissolution of Serpentinites (Tailings and waste rock) for use in indirect mineral carbonation
(2022-04-01)
Solid carbonates can be formed by indirect mineral carbonation using the pH swing method for CO2 storage. It occurs at low temperatures and pressures in four stages: acid dissolution, purification, carbonation, and recovery. ...
Design of Experiments for the Establishment of the Dissolution Test Conditions of Rupatadine Fumarate 10 mg tablets
(2019)
Design of Experiments (DoE) is a statistical model that aims to determine if the factors under study affect the response, and if so, it determines
the conditions under which this variable of interest can be optimized. In ...
On a dissolution-diffusion model. Existence, uniqueness, regularity and simulations
(Elsevier, 2015-10)
We perform a mathematical analysis of a model for drug dissolution-diffusion in non erodible nor swellable devices. We deduce a model and obtain a coupled nonlinear system which contains a parabolic equation for the dissolved ...
New insights into oxidative-reductive leaching of chalcopyrite concentrate using a central composite factorial design
(2022-04-01)
A response surface capable of describing the extraction of copper with high statistical confidence (R2 = 0.9973) was obtained using a central composite factorial design (CCD). The parameters used were the initial concentration ...
