The original sol-gel method developed at the Institute, which allows the sorbents to be obtained from non-traditional, easily available, and cheap raw materials, was used to synthesize the novel ion exchangers based on double hydrous oxides

The aim of this work was to investigate the sun light induced photodegradation as well as the photocatalytic degradation of pharmaceuticals and X-ray diagnostic agents (PhaDAs), and to follow their degradation pathways. The influence on the photolytic and photocatalytic degradation of the selected PhaDAs in the absence and presence of natural organic matter was investigated. Technical systems suitable for photocatalytic degradation and adsorption were developed and their applicability was checked. The advanced oxidation processes and adsorption experiments led to promising data for the elimination of the PhaDAs.

Applied research data on advanced photocatalytic methods aimed at treatment of contaminated aqueous phase is presented. Phenol and chloroorganic pesticides (as model compounds) besides actual wastewater samples were UVphotodegraded using suspended TiO or UV/HO/air systems. Titanium dioxide catalysts modified with non-metal elements were used to photodegrade phenols in visible light. Laboratory and pilot scale reactors were used and the effect of process scale-up investigated.

The effective, affordable removal of hazardous molecules, viruses and bacteria from water is of paramount importance. In this paper, we investigate the use of various novel colloidal and interfacial strategies for such removal. The objective of this work is to develop methodologies for the removal, in a costeffective manner, of bacteria and viruses from water, with the implication that such methodologies will be applicable to poorer countries which may not be able to afford the more expensive water treatments such as reverse osmosis.

Greenhouse studies were conducted to assess the potential of fly ash-organic waste co-disposal to enhance crop production.

Research on phytoremediation and phytotechnologies is proceeding at a different pace in the EU than in the USA. In fact although EU researchers have closed the gap on basics and fundamentals of phytoremediation with overseas researchers, a large gap of application exists in the extent of cases to which phytotechnologies are applied.

This study investigated the removal mechanisms of arsenic and heavy metals in constructed wetland systems. The biotic and abiotic processes in the wetlands and the influences of plants, soil and micro-organisms on arsenic and heavy metal removal were examined. Various small-scale constructed wetlands were set up in order to study and compare the removal efficiency of laboratory-scale wetland models and small-scale field test systems. In the field test systems, acid mine drainage (AMD) was used as an example of acidic wastewater contaminated with heavy metals.

Reduced soil leaching under nutrient-rich sewage effluent irrigation and biosolids compost application was tested as means to control leaching of nutrients, organic carbon, heavy metals and enteric bacteria.

Selected emergent plants (helophytes) were successfully used for degradation of TNT (2,4,6-trinitrotoluene) under conditions.

Plant capability to lower antimicrobial drug concentration, such as sulfonamide (Sulfadimethoxine) and a quinolone (Flumequine), widely used in intensive farming, has been tested in laboratory models already set up in previous experiments.
