(54) СПОСОБ ОПРЕДЕЛЕНИЯ НИТРАТНОГО АЗОТА В ПОЧВАХ И ВОДЕ(54) METHOD FOR DETERMINING NITRATE NITROGEN IN SOIL AND WATER

Колориметрируют, примен   дл  этой цели невыцветающую эталонную шкалу сравнени  с диапазоном 0,05-10 мг/л нитрата.Colorimetry using a non-color reference reference scale for this purpose with a range of 0.05-10 mg / l nitrate.

Невыцветающую шкалу сравнени  готов т из препаратов, окращенных в карминовый и фиолетовый цвета. Например, из 0,12 мл туши цвета кармин и 0,23 мл водного раствора (1:140) фиолетовых чернил дл  авторучек (или туши) с добавлением 20 мл 48%-ного раствора этилового спирта.A non-flowering comparison scale is prepared from preparations that have been carmine-colored and purple in color. For example, from 0.12 ml of carmine color ink and 0.23 ml of an aqueous solution (1: 140) of violet ink for pens (or ink) with the addition of 20 ml of 48% ethanol solution.

Полученную смесь, имитирующую 10 мг/л 1Штратного азота, последовательно разбавл ют тем же раствором спирта от 10 до 0,05 мг/л нитрата. Оттенки полученной шкалы сличают с оттенками стандартных растворов и при надобности корректируют их увеличением или уменьшением объема фиолетового компонента.The resulting mixture, imitating 10 mg / l of 1 Nitrogen, is successively diluted with the same alcohol solution from 10 to 0.05 mg / l of nitrate. The shades of the scale obtained are compared with the shades of standard solutions and, if necessary, corrected by increasing or decreasing the volume of the violet component.

Примен емые дл  анализа пробирки должны иметь строго одинаковый диаметр и емкость.Tubes used for analysis should have exactly the same diameter and capacity.

Невьпдаетающую эталонную шкалу необходимоNon-pending reference scale needed

оберегать от пр мых солнечных лучей и хранить в темном месте.protect from direct sunlight and store in a dark place.
