Pyrolysis and combustion of electronic wastes

摘要: Abstract The decreasing costs and increasing availability of electronic products all kinds, including mobile phones, audio video equipment, personal computers their accessories, coupled with advances in technology that rapidly make these obsolete, foretell a growing disposal problem. materials employed the present work were phone (printed circuit board + casing) printed boards alone. Pyrolysis combustion runs at 500 °C horizontal laboratory furnace performed, analyses gas semivolatile fractions (including dioxins furans “dioxin-like” PCBs) are shown. analysed for PCDD/F PCB content order to establish level pollutant samples themselves. Some TG–MS experiments carried out better know thermal decomposition wastes identify some compounds emitted during controlled heating materials. Furthermore, kinetic study (EC) both nitrogen nitrogen:oxygen atmospheres using different rates is presented.
