Abstract
Изобретение относитс к способам определени рутени и может быть использовано при анализе природных и промышленных объектов с целью повышени селективности анализа. Дл этого к пробе приливают свежеприготовленный раствор дитиопирилметана в 2 M HCL и нагревают на вод ной бане. Раствор внос т в экстракционную воронку, приливают раствор перхлората натри , смесь хлороформа и изобутанола и экстрагируют в течение 1 мин. Измер ют оптическую плотность экстракта и по градуировочному графику определ ют содержание рутени . Оптимальное объемное соотношение хлороформа и изобутанола (4-6):3. Способ позвол ет определить рутений в присутствии платиновых металлов, золота, свинца, молибдена, сурьмы, кобальта и серебра. 2 табл.The invention relates to methods for determining ruthenium and can be used in the analysis of natural and industrial objects in order to increase the selectivity of the analysis. To do this, a freshly prepared solution of dithiopyrilmethane in 2 M HCL is added to the sample and heated in a water bath. The solution is introduced into the extraction funnel, sodium perchlorate solution, a mixture of chloroform and isobutanol are poured in and extracted for 1 minute. The optical density of the extract is measured and the ruthenium content is determined by a calibration curve. The optimum volume ratio of chloroform and isobutanol (4-6): 3. The method allows ruthenium to be detected in the presence of platinum metals, gold, lead, molybdenum, antimony, cobalt and silver. 2 tab.
Description
В табл. 3 приведены данные по токсичности и стоимости реагентов, примен емых в известном и предлагаемом способах.In tab. Table 3 shows the toxicity and cost of the reagents used in the known and proposed methods.
Таким образом, указанный способ позвол ет исключить применение токсичных реагентов, расширить круг объектов, из.которых может вестись извлечение, и снизить стоимость одного определени хрома (VI) в 30 раз.Thus, this method eliminates the use of toxic reagents, expands the range of objects from which extraction can be carried out, and reduces the cost of one definition of chromium (VI) by 30 times.
