Compare to other documents, our study was for the first time validated the quality criteria of ICP-MS for analyzing nineteen metal levels in wastewater samples. The application of this method was then tested by analyzing nineteen metal levels in twenty-three wastewater samples in the Tham Luong Canal in Ho Chi Minh City. Based on these results, the correlation of the concentration of these metals in wastewater samples was determined.

This study investigated trace essential metals (Cu, Zn and Cr) and non-essential metals (Pb, Cd and Hg) in water, sediment and tissues of water spinach, snake head fish and swamp eel from the Saigon River. Sampling was conducted from January to December 2004 at three sites. Three water and sediment samples, edible parts of twenty water spinach (Ipomea aquatica) samples (leaves and stems), twenty snake head fish (Channa striata) and twenty swamp eels (Monopterus albus) were collected at each site.

The main aim of this study is to investigate utilising root-like architectures to improve the interfacial strength of pin-integrated hybrid composite-metal structures. Joints are critical elements in aircraft structures and require special consideration due to their vital role in the structural integrity of airframes. Although bonded and bolted systems are used commonly in engineering applications, pinning technologies have shown tremendous potential for hybrid joints.

This Master's thesis aims to document the research process into the synthesis of 2D AlPO4 via a liquid metal synthesis pathway. The synthesised 2D AlPO4 will then undergo qualitative and structural analysis, after which it will be characterised via advanced techniques to determine piezoelectric characteristics, as well as the exploration of the ability of the synthesised material to absorb heavy metals.

The main aim of this investigation was to develop a low-cost solution to remove trace metals from the aqueous phase using biochar. This study investigated (i) the effect of giant reed-based biochar produced at varying temperatures in the treatment of aqueous solutions polluted with lead; and (ii) how the production of biochar at different temperatures affected its adsorption capacity for lead from the aqueous phase.

The calculations showed that the results are comparable to the best MOFs for the hydrogen storage up to date. The results also elucidated that the gravimetric hydrogen uptakes depend on the special surface area and pore volume of the MIL-88s. These important structural features, if properly improved, lead to an increase in the capability of hydrogen storage in MIL-88s.
