Fig. 4From: A simple co-precipitation sorbent-based preconcentration method for the analysis of fungicides in water and juice samples by high-performance liquid chromatography coupled with photodiode array detectionEffect of SDBS concentration on the extraction performance of target fungicides (100 µg/L each). Conditions: 300 mmol/L MgCl2 (150 μL), 0.5 mol/L NaOH (200 μL), and 10 mmol/L SDBSBack to article page
