Effluent Characteristics

The objectives of this work were to carry out a complete characterization of textile wastewater, resulting from a textile unit located in the Marrakesh region. A physico-chemical characterization has been performed, focused on organic and toxicological aspects. The cladoceran Daphnia magna was used as the sensor organism and lethal concentration as a criterion to measure the toxicity of textile wastewater. The physico-chemical and toxicological status of a local textile effluent showed considerable values limitation, when compared to the European Union standard limit and Moroccan guide level and other studies. In view of those characteristics, the wastewater effluent from the textile industry should be considered to be treated before discharge to the environment.

Harbour Sediments

Dredging is a very important procedure within harbour management. Italian legislation regulates dredging activity requiring high number of sampling stations and physico chemical and biological parameters but the criteria for their interpretation are not reported adequately. The comprehension of the information included in the data is a very critical step of every dredging activity of harbour sediments and the traditional examination of these large database (searching of average values of pollutants or simple correlations among pollutants) does not make easy their interpretation. So the included information can result hidden than clarified. With the aim to perform a complete characterization of the examined area we applied Principal Components Analysis (PCA) and Cluster Analysis (CA) to the examination of a complex data matrix consisting of the physico chemical characterization (sediment texture, heavy metals, organic pollutants) of the industrial canal sediments in Livorno harbour. The multivariate methods allowed to study the general distribution of pollutants in the Livorno canal, clarifying also the significant parameters for the characterization of the system.

Double Hydroxides

The fourth generation cephalosporin antibacterial agent, cefepime, was loaded into layered double hydroxides for enhancing antibiotic efficiency, reducing side effects, as well as achieving the sustained release property. The intercalation of antibiotic into the inter-gallery of ZnAl-layered double hydroxide (LDH) was carried out using ion exchange method, by this constituting a nano-sized organic-inorganic hybrid material for a controlled release novel formulation. Although cefepime is a broad spectrum antibiotic, it has various adverse effects and a significant degradation rate. Thus, the preparation and physico-chemical characterization of nanomaterials able to intercalate this drug is an important study for medical and pharmaceutical field. The antibiotic inclusion into LDHs nanostructure was confirmed by advanced characterization techniques and the release profile of cefepime was analysed with the respect to pH of the simulated media.
