Abstract
The effect of TMAH(tetramethylammonium-hydroxide) on the conversion of urea to bicarbonate by the
immobilized enzyme was investigated. Urease was covalently immobilized on the magnetic particles, and it
facilitated the conversion of urea to bicarbonate in the absence of TMAH. The conversion did not change until
the concentration of TMAH reached 10 ppm, but decreased by less than half at 20 ppm. The results of this study
seem to be useful in deriving the conditions for recycling wastewater generated in the semiconductor process.
