Ionic Liquid-Based Centrifuge-Less Cloud Point Extraction of a Copper(II)-4-Nitrocatechol Complex and Its Analytical Application
{{output}}
A novel centrifuge-less cloud point extraction (CL-CPE) method was developed for the spectrophotometric determination of copper(II) using 4-nitrocatechol (4NC) as the chelating agent. The extraction system utilizes a mixed micellar phase composed of the nonion... ...
