Effects of heat on the alkali extraction of humic substances from peatSolutions of 0.1M and 0.25M potassium hydroxide (KOH) were used to extract the humic substances from two different types of peat (sphagnum and Carex) at 20, 50 and 80掳C. The effects of temperature on the yield of ...
Ultimately, ageing causes the oxidants to decompose and the fuel to onse, both of which result in reduced ZPP performance. Full size image To replicate the effects of ageing on pyrotechnic substances, work has been done to establish the effects of thermal and humidity conditions20,21,22,23,...
