Ultrasound-activated peracetic acid to degrade tetracycline hydrochloride: Efficiency and mechanism

Construction of a SnS2/TiO2 S-scheme heterostructure photocatalyst for highly efficient photocatalytic degradation of tetracycline hydrochloride

“…8, the photodegradation process of TC-HCl includes demethylation, deamination, deoxygenation, hydroxylation, and break removal of the piperazine ring. 53 In path 1, hydroxylation, demethylation, and deamination of TC-HCl macromolecular groups yielded P1 ( m / z = 461), P2 ( m / z = 433), P3 ( m / z = 419), and P4 ( m / z = 371). P4 ( m / z = 371), P5 ( m / z = 279) and P6 ( m / z = 210) intermediates obtained with the piperazine ring breakage, deamination and dehydroxylation.…”

Chemiluminescence‐assisted study on a peracetic acid‐based advanced oxidation process activated with cobalt phosphide

“…Additionally, the influence of PAA concentration was further investigated, and the best CL response (Figure S8c) and degradation efficiency (Figure S6c) were obtained at 0.2 mM PAA. However, decomposition and CL emission were slightly inhibited when the concentration of PAA was increased to 0.4 mM, possibly because of the elimination effect of superfluous PAA to ROS [29]. In addition, the flow rate also had an effect on CL emission, and the optimal CL response was observed at 70 rpm (Figure S8d).…”

Overlooked Role of Coexistent Hydrogen Peroxide in Activated Peracetic Acid by Cu(II) for Enhanced Oxidation of Organic Contaminants

“…Nevertheless, PAA alone could only directly degrade certain organic contaminants with electron-rich structures (e.g., sulfur moiety, aromatic ring, and CC bond) . Up to now, a number of activation strategies have been proposed to enhance the oxidative performance of PAA, such as energy input (e.g., ultraviolet, , heat, electrochemistry, microwave, and ultrasound), metal catalysts (e.g., homogeneous − and heterogeneous − transition metals), carbon materials, , and anionic catalysts (e.g., phosphate, bromide, , iodine, , chloride, and nitrite), etc.…”
