The microstructures, mechanical properties, and corrosion resistance of ZM21 magnesium alloys with a wide range of calcium （Ca） addition （0.1-1.6 wt%） were investigated. Results showed that the mechanical properties and corrosion resistance were improved with Ca addition because of grain refinement and formation of Ca2Mg6Zn3. However, these properties were deteriorated when Ca contents reached 1.6 wt%. The optimal Ca content of alloys was 0.7 wt%; alloy with this Ca content showed good mechanical performance and corrosion resistance, having a strength of 260 MPa, an elongation of 21.5%, and an average weight loss of 0.77 mg/（cm^2 days）.

Photocatalytic oxidation(PCO) process is an effective way to deal with organic pollutants in wastewater which could be difficult to be degraded by conventional biological treatment methods. Normally the TiO 2 powder in nanometre size range was directly used as photocatalyst for dye degradation in wastewater. However the titanium dioxide powder was arduous to be recovered from the solution after treatment. In this application, a new form of TiO 2(i. e. pillar pellets ranging from 2 5 to 5 3 mm long and with a diameter of 3 7 mm) was used and investigated for photocatalytic degradation of textile dye effluent. A test system was built with a flat plate reactor(FPR) and UV light source(blacklight and solar simulator as light source respectively) for investigating the effectiveness of the new form of TiO 2. It was found that the photocatalytic process under this configuration could efficiently remove colours from textile dyeing effluent. Comparing with the TiO 2 powder, the pellet was very easy to recovered from the treated solution and can be reused in multiple times without the significant change on the photocatalytic property. The results also showed that to achieve the same photocatalytic performance, the FPR area by pellets was about 91% smaller than required by TiO 2 powder. At least TiO 2 pellet could be used as an alternative form of photocatalyst in applications for textile effluent treatment process, also other wastewater treatment processes.
