AB  - In this study, coarse sand-supported zero valent iron (ZVI) composite was 
      synthesized by adding sodium alginate to immobilize. Composite was detected by 
      scanning electron microscope (SEM), X-ray diffraction (XRD), and X-ray 
      fluorescence (XRF). SEM results showed that composite had core-shell structure 
      and a wide porous distribution pattern. The synthesized composite was used for 
      degradation of 2,4-dichlorophenol (2,4-DCP) contamination in groundwater. 
      Experimental results demonstrated that degradation mechanism of 2,4-DCP using 
      coarse sand-supported ZVI included adsorption, desorption, and dechlorination. 
      2,4-DCP adsorption was described as pseudo-second-order kinetic model. It was 
      concluded that dechlorination was the key reaction pathway, ZVI and hydrogen are 
      prime reductants in dechlorination of 2,4-DCP using ZVI.
