Indirect measurement of frother concentration based on l-CCC curves
(Elsevier, 2016)
The local critical coalescence concentration l-CCC presents a relationship between frother concentration and the gas flow rate Q(g)' at which coalescence starts to occur at a capillary tube. Such a relationship is used in ...
Estudio de la xantación de alginato y su interacción con metales pesados en medio acuoso

Adsorción de mercurio y cadmio en carbón subbituminoso oxidado-xantado, sulfonado o activado y resina sintética comercial
(Bogotá : Universidad de Ciencias Aplicadas y Ambientales, 2015, 2015-01)
The combustion of low rank coal produces environmental impacts due to its low heat of combustion and high heteroatom content which has promoted its alternative uses as an adsorbent. ...
Study of absorption, emission and EDS properties of Pr3+ incorporated in a SiO2 matrix by sol-gel method
(2011)
This paper deals with a study of the oxidation processes of the PbS-sodium isopropyl xanthate system in alkaline conditions (pH 8, similar to flotation circuits Pb-Cu) by using cyclic voltammetry and Electrochemical Impedance ...
