AB  - In the present work, three-dimensional (3D) and flower-like SnS(2) materials were 
      coated on the surface of Fe(3)O(4)@nSiO(2) through an in-situ growth method. The 
      3D architecture could avoid the accumulation and reaggregation with better 
      stability and was beneficial for the exposure of more active sites. The prepared 
      magnetic SnS(2) composites were used for the enrichment of sulfonamide 
      antibiotics (SAs), and various experimental parameters affecting the extraction 
      efficiency were investigated. The results showed the equilibrium of extraction 
      and desorption towards target SAs could be reached within 3 min by using the 
      Fe(3)O(4)@nSiO(2)-SnS(2) composites. Under optimized conditions, the proposed 
      approach possessed good linearity in the range of 0.1-200 ng.mL(-1) with 
      correlation coefficients r(2) above 0.9964 and low limits of detection (LODs) 
      from 0.025 to 0.250 ng.mL(-1) for the five target SAs. Moreover, good 
      repeatability was obtained with the intra-day and inter-day precision in terms of 
      relative standard deviations (RSDs) within 1.1%-10.8% and 7.4%-13.1%, and the 
      recoveries under three spiked concentrations were between 81.8% and 119.7% with 
      adequate accuracy. Different samples including tap water, milk and honey were 
      collected for magnetic solid-phase extraction and determination of target SAs by 
      using the obtained Fe(3)O(4)@nSiO(2)-SnS(2) composites to demonstrate the 
      utility. All the results indicated that the proposed method had great potential 
      for effective preconcentration and determination of SAs in complex samples.
