Infrastrutture, campagna e tessuti urbani a Partinico. Tra la SS113 e viale dei Platani
The new district connects, along the north-south direction, Partinico with the train station and, in the east-west direction, it opens on an agricultural urban park between viale dei Platani and the SS 113 road. The park and the quarter are a unified composition, characterized by the continuity of agricultural soils. The residential buildings are crossed on the ground floor by fields of gerberas and chrysanthemums and ditches that are part of the network of the pedestrian and cycle park, whose spatiality is articulated through the different texture of the cultivated species, from flowers to vegetables, from vineyards to orchards, by citrus groves and olive groves. From the agricultural urba…
Influence of hydrogen peroxide on the kinetics of phenol photodegradation in aqueous titanium dioxide dispersion
Abstract The influence of hydrogen peroxide on the phenol photodegradation rate under near UV radiation was investigated in homogeneous and heterogeneous systems: the heterogeneous systems were aqueous dispersions of titanium dioxide (anatase). The hydrogen peroxide photodecomposition reaction was also investigated for all the systems used. The highest rate of phenol photodegradation was observed in the heterogeneous system for the contemporary presence of hydrogen peroxide and oxygen. The rate equations for phenol photodegradation and hydrogen peroxide photodecomposition for both systems were obtained. A mechanistic model able to explain the main experimental results is also proposed.
