• effective (Figure 1b) and after 1170 minutes of the sorption process MP still remained in the waste solution as p-NP. The result using Ni–Al mixed oxide as sorbent was surprising, as it did not promote the degradation of MP (Figure 1c). Figure 2 shows the MP degradation performance to p-NP of Mg–Al, Zn–Al
