The aim of this paper is to study the uranil-1 ignite link and the determination of the funtional groups which participate in it For that, the complejation of uranium with sodium bicarbonate have been studied and the kinetic equation of the system obtained. Later, through iR spectroscopy the funtional groups participating in the link with the uranil ion have also been obtainedspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/LignitesHumic acidsKineticsjournal articleopen access
