3.1. Effect of experimental factors
A hydrometallurgical method, namely leaching using hydrochloric
acid,was applied to separate aluminum and plastic in WPBs,
which facilitates the recycling of WPBs. The effects of temperature,
time, liquid/solid ratio, HCl concentration and agitation on separation
of Al from PVC in WPBs were investigated under fixed
conditions.
