Groundwater Arsenic Analysis and Removal using Novel Nanomaterials 

  Arsenic (As) exposure threatens human health. Accurate field As speciation analysis and its effective removal are of great importance. With the explosive development of nanofabrication, we synthesized Fe3O4@Ag magnetic SERS substrate as both an active As accumulator and a strong surface Raman enhancer. With a detection limit of 10 mg/L and a linear SERS response for As concentrations up to 1,000 mg/L, this in situ SERS platform allows easy and reliable detection and identification of As species in multiple matrices. As removal from water is achieved using nano-TiO2 based adsorbent. Due to its high affinity to TiO2, As was reduced to lower than 10 μg/L from 300-800 μg/L in raw water, satisfied the requirement of the drinking water standard. The total urinary As concentration from volunteers of local residences, ranging from 970 to 2,080 μg/L before groundwater treatment, decreased to the range 32-73 μg/L in 15-33 days.
