Sodium hypochlorite (NaClO) solution is wildly used to remove membrane fouling-derived organic materials and restore flux, which can result in the formation of halogenated by-products. To reduce by-products, a combined cleaning process with NaClO peroxides including hydrogen peroxide (H2O2), peroxydisulfate (PDS), peroxymonosulfate (PMS) were applied offline mode fouling. It was found that all ...

Five primaquine (PQ) analogues have been isolated by peroxydisulfate oxidation and were tested for antimalarial activity against Plasmodium yoelli infected mice. To develop them as promising antimalarial agents in-silico druglikeness studies were carried out. The analogue 6-Methoxy-5,8-di-(4-amino-1-methylbutyl-amino)-quinoline [P1] was found to be promising antimalarial agent as it was found n...

Thermosensitive polymer hydrogel particles with size varying from 480 to 620 nm were prepared through precipitation copolymerization of N-isopropylacrylamide with N,N'-methylenebisacrylamide (MBA) in water with ammonium persulfate as the initiator. Only polymer hydrogels without any coagula were obtained when MBA concentration in the monomer mixture was kept between 2.5 and 10.0 wt%; with incre...

Acrylate grouting material has been widely used in dams, tunnels and other underground buildings. This paper introduces the basic components of acrylate grouting material, then the reaction mechanism and dynamics of gelation process are discussed based on the theory of free radical polymerization. By measuring the relationship between gelation time and the concentration of initiator ammonium pe...

The metal-free synthesis of 2-substituted and 2,3-disubstituted morpholines through a one-pot strategy is described. A simple and inexpensive ammonium persulfate salt enables the reaction of aziridines with halogenated alcohols to proceed via an SN2-type ring opening followed by cyclization of the resulting haloalkoxy amine.
