The oxidative decarboxylation of levulinic acid (LA) by silver(I)/persulfate [Ag(I)/S₂O₈²⁻] has been investigated in this paper. The effects of buffer solution, initial pH value, time and temperature and dosages of Ag(I)/S₂O₈²⁻ on the decarboxylation of LA were examined in batch experiments and a reaction scheme was proposed on basis of the reaction process. The experimental results showed that...

An alternative approach toward understanding and advancing hydrogel-based single walled carbon nanotube (SWNT) purification is described employed. Experimental atomistic modeling analysis of the leading hydrogel for SWNT purification, Sephacryl S200, affords creation gels that mimic its behavior in terms dependent interaction properties. This achievement introduces a generalized optimization me...

Abstract The role of high-valent Fe has rarely been explored in persulfate-based heterogeneous reaction. Herein, the existence Fe(IV) is verified a visible light-assisted FeTiO3/persulfate system using methyl phenyl sulfoxide as probe. FeTiO3/persulfate/light capable selectively degrading aromatic compounds with lower ionization potentials including tetracycline and bisphenol A by photo-generat...

Introduction. Azithromycin is among the broad-spectrum antibiotics that is widely available in various environmental systems and could have destructive effects on the ecosystem and human health due to its bacterial resistance. In this study, removal of azithromycin from wastewater using an advanced oxidation process of ultraviolet light with and without persulfate was investigated and effective...

The search for lightweight and low-cost anticorrosion coatings is particularly important in coastal environments with high salt humidity. Graphene-based are currently unable to provide long-lasting corrosion protection metals because of their “corrosion-promoting activity”, graphene-like materials, such as molybdenum disulfide (MoS2), beginning be anticipated its ability protect against metals....

cellulose was modified by polystyrene (ps) and polyacrylonitrile (pan) via free radical and living radical polymerization, and then cellulose was used as the matrix in the preparation of polymer/clay nanocomposite, through a solution intercalation method. for this purpose, first, the graft polymerization of styrene (st) onto cellulose fibers was performed by using suspension polymerization and ...
