Abstract:
1. An apparatus for removing heavy metals from a thin film, comprising: a transparent substrate having a front surface and a back surface; a heavy metal thin film deposited on said back surface; a laser for generating high density radiation; a scanning means for directing said high density radiation through said transparent substrate so that said high density radiation impinges upon said heavy metal thin film; a flowing liquid; said heavy metal thin film deposited on said back surface being disposed in contacting relation to said flowing liquid; a liquid bath container for containing said flowing liquid and collecting heavy metal that is ablated by said high density radiation; a filter for filtering said heavy metals from said liquid bath; whereby said heavy metal materials are effectively and efficiently separated from said liquid bath and collected in said filter for subsequent disposal or recycling.
