AB  - Chlorophenols (CPs) are still used as raw material or intermediate in some 
      industries. Photocatalytic oxidation is free from secondary pollution, but the 
      efficiency is restricted by some main factors. In this study, a novel high 
      efficiency tubular up-flow magnetic film (TUMF) photocatalytic system was 
      investigated based on the magnetic lanthanum doping core-shell 
      Fe(3)O(4)@SiO(2)@TiO(2) (La-FST) nanoparticles. When the dosage of La-FST was 0.4 
      g/L, the flow velocity was 94.2 mL/min, and the circulated irradiation of 15 W 
      maintained 40 min, the average removal rate of 2,4-dichlorophenol (2,4-DCP) was 
      reduced significantly from 10 mg/L to 0.0803 mg/L by TUMF system, meeting the 
      limits of the particular items (0.093 mg/L) from national environmental quality 
      standards for surface water, avoiding the problem of photocatalyst separation and 
      loss. The photoinduced holes (h(+)) was the key active radical to oxidize 
      2,4-DCP, and the main factors of TUMF system could be well controlled to achieve 
      satisfactory effluent quality. A prediction method of photocatalytic reaction 
      time in a multistage series TUMF system was established to remove 2,4-DCP from 
      100 mg/L to 0.5 mg/L, saving 86 min. The novel high-efficiency TUMF system 
      provides a technical selection for the photocatalytic degradation of CPs and 
      other refractory organics.
