Researchers from Stockholm University (Stockholm, Sweden) and Nankai University (Tianjin, China) used a serial mixed-mode cation-exchange and anion-exchange solid-phase extraction (SPE) method to extract 15 basic, neutral, and acidic pharmaceutical compounds from wastewater.
Researchers from Stockholm University (Stockholm, Sweden) and Nankai University (Tianjin, China) used a serial mixed-mode cation-exchange and anion-exchange solid-phase extraction (SPE) method to extract 15 basic, neutral, and acidic pharmaceutical compounds from wastewater. Separate mixed-mode cation- and anion-exchange columns were used in series. They used high performance liquid chromatography with quadropole time-of-flight mass spectrometry to analyze the extracted compounds. The recovery for the SPE method in the analysis of sewage treatment plant wastewater averaged 80%.
Dispersive Liquid-Liquid Microextraction: A Review and Roundup of Green Sample Prep Advancements
May 15th 2024The still relatively new technique has distinct advantages, but a few of those benefits make it incompatible with some of the currently accepted principles of green sample preparation.
