Samples were collected and prepared by assorting
front and back parts as housing cover of used TV sets
which were collected through EPR system. Sampling
was focused on Company A and B as leading companies
in South Korea dealing in domestic display industry
and products of foreign brands. After identifying
product information on wasted TV sets, they were
assorted into front and back cover. Initially all metals
except stranded copper wire and thin non magnetic
cables were removed by magnet and hand sorting
technique. Samples were grind to 2 mm size followed
by gentle washing by nano pure distilled clean water
and finally preserved for subsequent analysis
(Spalvins, 2008).
