The distribution of engineered nanoparticles (ENPs) in municipal wastewater treatment systems

Choi S., Eichhorn J., Johnston M., Huang C.P., University of Delaware, US

The objective of this research was to develop a method reliable for the detection and quantification of engineered nanoparticles in municipal wastewater treatment systems. Wastewater and sludge samples were sampled from four regional municipal wastewater [...]

Thermostability of TiO2 nanoparticle and its Photocatalytic Reactivity at Different Anatase/Rutile Ratio

Tseng Y-H, Lin H-Y, Kuo C-S, Li Y.Y., Lin H-Y, Huang C.P., Industrial Technology Research Institute, TW

Thermostability study of commercial P25 TiO2 nanoparticles was carried out by ascending annealing temperature from 400 to 1100 oC. The thermostability of TiO2 structure was measured by X-ray diffraction (XRD). Anatase-Rutile phase transition occurred only [...]

Monometallic nano-catalysts for the reduction of perchlorate in water

Wang D.M., Lin H-Y, Huang C.P., University of Delaware, US

Perchlorate removal in a clean, cost-effective and public-acceptable approach is one of the important issues for current drinking water treatment. Catalytic membrane (CM) was prepared by coating monometallic catalysts of the nano-size onto supports by [...]

Growth and Some Enzymatic Responses of E. coli to Photocatalytic TiO2

Erdem A., Metzler D., Chou H.W., Lin H-Y, Huang C.P., University of Delaware, US

The effects of photocatalytic nano-TiO2 on the survival or die-off of E. coli (e.g. TK2) were investigated under ambient conditions. Experimentally, a 28-h E. coli culture was exposed to photocatalytic nano-TiO2 at various concentrations, e.g., [...]
