Analyses by XRF of three Ashed Samples of Toner Powder
Source publication
Globally, an estimated 1.1 billion printer toner cartridges are sold each year with over 500 million of these ending up in landfills. In this work the potential for recovering iron oxide and carbonaceous materials from waste toner powder is demonstrated through the iron oxide-carbon composite pellet approach. Composite pellets of low-grade nonmagne...

... samples of toner ash powder were ashed and characterised by XRF analysis. The results are shown in Table 1. Significant amounts of iron oxide, ranging from 80.1 wt% to 84.4 wt% Fe2O3 can be observed in all the three ashed samples of the toner powder, similar to earlier observation by Gaikward et al., (2017). ...
