Fig. 8From: Molecularly imprinted polymers as solid-phase and dispersive solid-phase extraction sorbents in the extraction of antiretroviral drugs in water: adsorption, selectivity and reusability studiesEffects of contact time on the adsorption efficiency of ARVDs. Experimental conditions were: initial concentration of ARVDs—50 mg L−1, sample pH—6, adsorbent mass—40 mg, and sample volume—5 mLBack to article page
