Types of metal hydroxides co-precipitation methods for the preconcentration of target fungicides (100 μg/L each). LDH: 300 mmol/L MgCl2 (90 μL), 300 mmol/L AlCl3 (30 μL), 0.5 mol/L NaOH (100 μL); Mg(OH)2: 300 mmol/L MgCl2 (90 μL), 0.5 mol/L NaOH (100 μL); Al(OH)3: 300 mmol/L AlCl3 (90 μL), 0.5 mol/L NaOH (100 μL); the addition of surfactants (SDS or SDBS): 10 mmol/L (350 μL)
