With a total of 2 patents, her work has implications for both environmental and industrial applications.

Latest Patents

Sandra's latest patents focus on advanced methods for uranium extraction. The first patent involves a concentrated sulphuric acid treatment of an alkylphenyl acid phosphate. This method allows for the extraction of uranium in the tetravalent state using a mixture of mono- and di(alkylphenyl) esters of orthophosphoric acid. The process includes stripping the pregnant extractant with a suitable solution and recycling the barren extractant. The second patent addresses the deprotonation of an alkylphenyl acid phosphate extractant. This innovation enhances the extraction process by oxidizing uranium to the hexavalent state and reducing hydrolysis of the extractant through various chemical treatments.
