SOIL & WATER REMEDIATION
The following advanced remediation technologies require R&D support in order to achieve full commercialization.
Field Monitor for organochlorines in soils/sludges.
A field monitor is being developed by our group for rapid analysis of organochlorines in contaminated soils and sludges.
Unlike laboratory based procedures, this monitor requires minimum sample preparation and gives an almost instantaneous result on the total concentration of organochlorines in a soil or sludge sample.
This monitor is to be used during the cleanup of contaminated sites, and 'on the spot' results obtained using the equipment can substantially reduce the remediation cost by providing :
Already, a provisional patent has been lodged with the Australian Patent Office. We are now seeking collaborators for developing the invention to a commercial product.
- fast assessment of the initial extent of contamination
- on field indication of the current extent of contamination during treatment
- more effective targeting of treatment activities for remediation of 'hot spots'.

New photocatalyst for photocatalytic degradation of organic pollutants in water.
TiO2-mediated photocatalytic oxidation as a means for destroying organic pollutants in water has been the subject of our research for many years. Potentially, photocatalytic oxidation could be the cheapest and safest way for destroying organic pollutants in water. The main obstacle for it being used as a large scale treatment process for wastewater is its relatively slow rate of reaction. This makes it less economically attractive when compared with other oxidation processes.
Recently, our group has made a number of new photocatalysts that have reaction rates several times faster than what can be achieved by commercially available ones.
Our object is to improve the rate further by optimising the procedure for making these photocatalysts. They can be then used routinely for the destruction of organic pollutants in either water or air. We seek commercial collaborators or funding bodies that can help us take the project to its next phase of development.
