Утилизация отходов
Incineration of phenoxys is
effective in 1 second @ 982
C, using a straight combustion
process or @ 482℃
using catalytic combustion. Over 99%
decomposition was reported when small amounts of 2,4-D
were burned in a polyethylene bag. See “References”
for additional detail. In accordance with 40CFR165, follow
(31); recommendations for the disposal of pesticides and
pesticide containers. Must be disposed properly by follow-
ing (100) Package (2) label directions or by contacting
