Finally, the oscillation time was optimized for extractions using ammonium hydroxide
solution 0.5% (v/v) with an oscillator at 160 rpm.
NMSO is a formaldehyde-free, macromolecule which is capable of crosslinking cellulose.
L-lysine was eluted by 2N ammonium hydroxide
We prepared a stock standard solution of uric acid in 1 mmol/L ammonium hydroxide
at a molar ratio of 1.7:1, according to Ellerbe s method.

In addition, both strategies merely dilute the ammonium hydroxide
functionality rather than eliminate it.
Certain component organisms of these biofilms produce urease, which hydrolyzes the urea in the patient's urine to ammonium hydroxide
. The elevated pH that results at the biofilm-urine interface results in precipitation of minerals such as struvite and hydroxyapatite.
Sydney airport later confirmed that the fumes were caused by ammonium hydroxide
, a cleaning agent, leaking into the air conditioning system.
According to the Department of Health (DOH), use of Siemens' ammonium hydroxide
product as a fertilizer will have no adverse impacts on public health or the environment when used as directed.
However, we have shown in this study that if the pendant acrylic acid groups are first pre-neutralized with aqueous ammonium hydroxide
and then ammonium carbonate is added prior to AZC addition, then colloidal stability is maintained and a stable ionomer dispersion is obtained.
Examples of bases are ammonium hydroxide
(NH4OH), calcium hydroxide (Ca(OH)2), and potassium hydroxide (KOH).
The pH of the slurry and rinse tank should be controlled with reagent-grade ammonium hydroxide
