The further outside of the optimum pH range a value is, the higher the mortality rates Other was to test biodegradability of quaternary ammonium cations are done by using bioassays and biodegradability tests with aquatic animals or several types of bacteria.
The further outside of the optimum pH range a value is, the higher the mortality rates for certain species. The biodegradability of quaternary ammonium cations can be tested by using bioassays and biodegradability tests with aquatic animals or several types of bacteria.
