“…A similar finding has been reported by Wang et al. [ 59 ]. In this study, the pH of the CIP solution was stable, which is most likely due to the large volume of the CIP solution, for which slight changes in the amount of H + and OH ‒ ions would not affect the acidity of the solution.…”

“…The generation of ozone microbubbles and nanobubbles using such an aerator pump has been reported in several studies [ 56 , 57 , 58 ]. It has been pointed out that the volumetric flow rate of gas is the most influential parameter for the efficiency of ozone microbubble production [ 59 ]. In this study, the flow rate used to generate ozone microbubbles was set based on our optimization study on different flow rates of gas.…”

“…The International Standards Organization is currently evaluating standards for ultrafine bubbles (ISO/TC 281) [31], and many details related to the mechanism of ultrafine bubbles remain unresolved. However, various application technologies, such as sterilization [32] and material decomposition [33], have been developed by applying cavitation generation. Studies on the extraction of collagen with dilute acetic acid solutions have been previously reported [5,[34][35][36][37], but an extraction method using a combination of dilute acetic acid and ultrafine bubbles has not been reported thus far.…”

Type I collagen is commonly used in medical materials and cosmetics. While it can be extracted from the skin and bones of mammals, marine collagen has attracted attention recently, since the use of mammalian collagen could result in zoonosis, and products containing mammalian collagen are avoided due to some religious beliefs. Chemical extractions using strong acids and alkalis, thermal extractions, and other nonconventional methods have been used for collagen extraction. However, there are few reports on environmentally friendly methods. Although heat extractions provide higher yields of collagen, they often cause collagen denaturation. Therefore, dilute acetic acid and ultrafine bubbles of oxygen, carbon dioxide, and ozone were used to extract type I collagen from tilapia scales. The extraction performance of the different conditions employed was qualitatively analyzed by SDS-PAGE electrophoresis, and the collagen concentration was quantified using circular dichroism spectroscopy by monitoring the peak intensity at 221 nm, which is specific to the triple helix of type I collagen. Collagen was extracted from tilapia scales with a yield of 1.58% by the aeration of ultrafine bubbles of carbon dioxide gas in a 0.1 M acetic acid solution for 5 h.

“…The abuse of antibiotics will induce the production of antibodies by bacteria, which will cause serious harm to the ecological balance of the water environment and human health after a large amount of accumulation. [1][2][3] Tetracycline (C 22 H 24 N 2 O 8 ) is a typical antibiotic, the molecule contains many hydroxyl groups, 4 enol hydroxyl groups and carbonyl groups, its chemical structure and structural model are shown in Figure 1. Tetracycline can form insoluble chelates with a variety of metal ions under neutral conditions.…”

In order to treat antibiotics organic pollutants in the water environment, the Pd/PANI/ITO composite electrode was prepared by the galvanostatic electrodeposition method in this paper. The surface morphology and electrocatalytic activity of the electrode were analyzed and tested. Using the degradation rate of electrocatalytic tetracycline wastewater as an indicator, the optimal parameter conditions for preparing the composite electrode were screened out: the optimal deposition current of PANI was 2 mA, and the deposition time was 10 min. The optimal deposition current for Pd is 2 mA, and the deposition time is 10 min. The optimal current for the degradation of tetracycline wastewater is 10 mA, and the relationship between the degradation current and the degradation time conforms to the pseudo-first-order reaction kinetics. The existence of ÁOH in the degradation process of tetracycline was verified by the coumarin fluorescence detection technology. Finally, the degradation process of tetracycline wastewater is analyzed. The results show that the intermediate products produced during the degradation of tetracycline are gradually cleavage of tetracycline molecules, and they are eventually converted into CO 2 and H 2 O.
