Bivalve shell waste has the potential to be used as a bio-filler. In this work, the dispersive component (γsd) of surface free energies of the surfaces of clam shell waste (CS) and commercial calcium carbonate (CC) were evaluated using inverse gas chromatography with both the Dorris–Gray method and the Schultz method. Their acid-base character was investigated as well. The mechanical properties of...
A centrifugal microfluidic device was developed for the rapid sequential determination of two critical environmental species, nitrate and nitrite, in water samples. The nitrate is reduced to nitrite and the nitrite is derivatized. The analytes are determined spectrophotometrically through the disc with a 1.4mm pathlength. The detection limits are 0.05 and 0.16mgL −1 for nitrite and nitrate...
Organic pollutants such as polycyclic aromatic hydrocarbons (PAHs) are present in the environment in increasing concentrations and so are of growing concern. Monitoring these species, particularly on-site, can be both difficult and expensive. This paper presents a novel miniaturised magnetically actuated liquid–solid extraction unit integrated in tandem with a filtration unit and a detection unit...
