| Research Abstract |
Highly efficient wastewater treatment systems were designed by using thermoresponsive polymers having functional groups that can react with desired environmental pollutants in water. Phenolic compounds and estrogens which have insufficiently been eliminated from water by conventional wastewater treatment processes were rapidly and nearly completely removed from wastewaters. By change the functional groups, the proposed method was applicable to the rapid removal of toxic metal ions in environmental waters and ortho-phthalaldehyde in antiseptic solutions for endoscopes. Moreover, temperature-independent coagulation methods were also developed and used for designing practical wastewater treatment systems.
