Abstract
Surfactant Sensor Based on Waveguide-mode Sensor with Hydrophobic Perforated Surface
Highlights
Surfactants are widely used in manufacturing plants and in homes as synthetic detergents
The results reveal that the detection of Tween 20 and sodium dodecyl sulfate (SDS) is possible at the concentrations permitted under the Water Quality Standard as stipulated by the Water Supply Law of Japan, 0.02 and 0.2 mg/l, respectively, using the waveguide-mode sensor with the hydrophobically treated perforated sensing plate
A surfactant sensor was configured by hydrophobic treatment of the surface of a waveguidemode sensing plate with nanopores
Summary
Surfactants are widely used in manufacturing plants and in homes as synthetic detergents. Lakes, and marshes are contaminated when effluent that contains surfactants is released into the environment. Agricultural chemicals include surfactants that are discharged into the environment when such chemicals are sprayed. The screening test for surfactants in rivers, lakes, and marshes of agricultural areas can serve as an effective means of detecting potential agricultural chemical contamination. The evaluation of water can be conducted in a laboratory, such a process is not economical because transporting water to a laboratory from the field is time-consuming and expensive. A method for conducting an on-site screening test to determine the level of contamination is desired
