The initials CCA indicate chromated copper arsenate, ACZA stands for ammoniacal copper zinc arsenate, and ACQ means alkaline copper quat.
12.
Increased sulfide has been shown to inhibit NH 4-N ( ammoniacal nitrogen, an ammonium salt ) uptake within the plant.
13.
He repeated experiments of Robert Boyle with ammoniacal copper salt solutions, in which air was absorbed, with an accompanying change of colour.
14.
Oxidation of the ammoniacal solution gives orcein, C 28 H 24 N 2 O 7, the chief constituent of the natural dye archil.
15.
Mr . D . Wilson, of Dublin, patented a method for purifying coal-gas by means of the chemical action of ammoniacal gas.
16.
The values of ammoniacal nitrogen in water or waste liquids are measured in milligram per liter and are used for specifying water treatment systems and facilities.
17.
The hydraulic main had a level of a liquid mixture of ( initially ) water, but, following use, also coal tar, and ammoniacal liquor.
18.
Levels of ammoniacal nitrogen ( from sewage ), acidity, heavy metal content, oxygen-depleting substances and sediment in the rivers are factored into the NWQS.
19.
This type of amendment creates acidic conditions ( pH less than 7 ) in the litter, resulting in more of the ammoniacal nitrogen being temporarily retained as ammonium rather than ammonia.
20.
The deep, 3 in . bore for the dairy factory, 70 ft . above sea-level in Rose St, was polluted with ammoniacal nitrogen and chlorides too were high.
