Application of Ozone Related Processes to Mineralize Tetramethyl Ammonium Hydroxide in Aqueous Solution

Table 1

The pseudo-first-order rate constant 𝑘_obs, half-life t _1/2, and correlation coefficients for degradation of TMAH by UV/O₃ at different pH values. (Experimental conditions: pH values were adjusted by H₂SO₄ and NaOH and fixed at a constant value during the whole reaction time; the other conditions were the same as in Figure 4(d).)

5.0	0.0313	0.917
7.5	0.0312	0.973
