Abstract

The authors regret In Section 3.1 on page 106, it was stated that: “The model obtained from this method is presented in Eq. (5) shows that initial concentration, pH0, pulse time, and process time have a positive effect on the process, and EC0 negatively affects the HA removal.” This sentence should be replaced by: “The model obtained from this method is presented in Eq. (6). It shows that initial concentration, pH0, pulse time, and process time have a positive effect on the process, and EC0 negatively affects the HA removal.” In Section 3.2 on pages 107 and 108, it was stated that: “According to Fig. 3a and b, the optimal values for response optimization were determined as 50 mg/L for initial concentration, 7 for initial pH, 10 min for pulse time, 500 μS/cm for electrical conductivity, and 70 min for operation time.” This sentence should be replaced by: “According to Fig. 3a and b, the optimal values for response optimization were determined as 50 mg/L for initial concentration, 7 for initial pH, 10 min for pulse time, 500 μS/cm for electrical conductivity, and 50 min for operation time.” In Section 3.3.1 on page 108, it was stated that: “According to Fig. 1, the removal of HA occurred mostly in the first 10 min.” This sentence should be replaced by: “According to Fig. 2, the removal of HA occurred mostly in the first 10 min.” In Section 2.3 on page 105, it was stated that: “Two L-shaped aluminium electrodes were embedded in the reactor in unipolar mode with an effective surface area of 100 cm2 at 1 cm distance from each other, and 20 pores with a diameter of 4 mm were created on the surface of each electrode.” This sentence should be replaced by: “Two L-shaped aluminium electrodes were embedded in the reactor in monopolar or unipolar mode with an effective surface area of 100 cm2 at 1 cm distance from each other, and 20 pores with a diameter of 4 mm were created on the surface of each electrode.” In Section 3.3.2 on page 109, it was stated that: “At the beginning of the process, the removal efficiency of HA versus time is increased with a steep slope, so that the highest HA removal rate in experiments shown in Fig. 1 occurs at 10 min; subsequently, the removal efficiency increases with a slight slope.” This sentence should be replaced by: “At the beginning of the process, the removal efficiency of HA versus time is increased with a steep slope, so that the highest HA removal rate in experiments shown in Fig. 2 occurs at 10 min; subsequently, the removal efficiency increases with a slight slope.” In Section 3.3.3 on page 109, it was stated: “Moreover, the increase in the removal of HA by increasing the initial pH (pH0) (from 3 to 7), process time (t) (from 10 to 70 min), and pulse time (Tpls), and pulse time (Tpls) (from 1 to 10 min), although the increase is not as significant as that in the case of initial concentration (C0).” This sentence should be replaced by: “Moreover, the increase in the removal of HA by increasing the initial pH (pH0) (from 3 to 7), process time (t) (from 10 to 70 min), and pulse time (Tpls) (from 1 to 10 min), although the increase is not as significant as that in the case of initial concentration (C0).” The authors would like to apologise for any inconvenience caused.
