Preparation of magnetic mesoporous metal-phenolic coordination spheres for extraction of crystal violet and leuco-metabolites in fish

Preparation of tannic acid and l-cysteine functionalized magnetic composites for synergistic enrichment of N-glycopeptides followed by mass spectrometric analysis

“…1–3 Due to its abundant hydroxyl groups, TA can not only chelate with metal ions but also form π–π interactions and hydrogen bonds with other functional groups. 4–6 Therefore, the applications of TA and its derivatives are frequently found in the area of separation and adsorption, such as metal ions, 7,8 dyes, 9,10 drug compounds, 11,12 and surface active agents. 13 When used as an adsorbent, TA often needs to be imbedded with substrates, e.g.…”

“…13 When used as an adsorbent, TA often needs to be imbedded with substrates, e.g. , Fe 3 O 4 , 9,14 SiO 2 , 15,16 and graphene oxide. 17,18 Among them, magnetic Fe 3 O 4 is an attractive option of substrates due to its advantages of rapid separation, simple preparation, good biocompatibility, and low cost.…”

Ultrasonic role to activate persulfate/chlorite with foamed zero-valent-iron: Sonochemical applications and induced mechanisms

“…A series of trace triphenylmethane derivatives detected in aquatic environment with low concentration (<μM level) as emerging contaminants have drawn the attention [1] , therein no lack of triphenylmethane crystal-violet (tpm CV ). Besides as the dye, the tpm CV ( Fig.…”

“…S1 a), could be used not only in clinical treatment, but also as antimicrobial and antiparasitic agents in aquaculture to treat and prevent fungal and protozoal infections [2] . However, the United States, the European Union, China, and others have not approved the use of tpm CV in aquaculture due to it with the possible carcinogen, mutagen and teratogen effects [1] , [2] , [3] . Even so, the use of the prohibited and persistent tpm CV would be common occurance, leading to its frequent detection in aquatic environment.…”

“…Specially, the bio-concentration of organisms made tpm CV convert into leuco crystal-violet ( L tpm CV , Fig. S1 b) (more toxic and more difficult to be metabolized) [1] , [3] , which might be seen as the persistent pollutants. …”
