案例1:100公升水需下多少的甲醛(form aldehyde )含量 37﹪的福馬林溶液?
25PPM的量=>25ml x 100(水量)/1000=2.5ml
30ppm的量=>30ml x 100(水量)/1000=3ml
案例2:100公升水需下多少的甲醛(form aldehyde )含量 24﹪的福馬林溶液?
25PPM的量=>25ml x (100(水量)/1000) x1.54=3.85ml
30ppm的量=>30ml x (100(水量)/1000) x1.54=4.62ml
1.54=37/24
要是14﹪的
就是
37/14=2.64倍
25PPM的量=>25ml x (100(水量)/1000) x2.64=6.6ml
30ppm的量=>30ml x (100(水量)/1000) x2.64=7.92ml
