Microwave-assisted regeneration of hypercrosslinked polymeric adsorbent saturated with nitrophenols.
Thermal regeneration of hypercrosslinked polymeric adsorbent (HPA) was performed at 67 degrees C. Experiments were carried out using a multimode microwave oven operating at 2450 MHz and a thermostatic water bath so as to compare the effect of the different heating mechanisms on the regeneration efficiency of the HPA saturated with nitrophenols. The temperature rise action of the heterogeneous regeneration system under microwave irradiation was described. Additionally, a complete structure and chemical characterization of the regenerated HPA was also carried out in order to study the influence of the subsequent regeneration cycles on the structure and the adsorption capacities of the adsorbents. Structure characterization of the regenerated HPA was accomplished by means of the analysis of FTIR spectra.A well-known matador has been killed during a bullfight in eastern Spain, the first such incident to occur in the country this century.

The fight was taking place at the festival Feria del Angel in Teruel, during an event which was being shown live on TV.

Professional bullfighter Victor Barrio, 29, was killed by a bull which flipped him over with a horn, then continued to gore and push him along the ground.

Bystanders immediately rushed to help but Mr Barrio had already sustained severe injuries. Doctors were unable to save him and he died in hospital.

The festival was suspended after the incident, which was broadcast live on Spanish television.

The bull was called Maños, according to El Mundo, and weighed 529 kilos.

Televison footage of the event showed Maños with several spears
