Description

(5) СПОСОБ ОПРЕДЕЛЕНИЯ БОРА В СПЛАВЕ ФЕРРОБОР (5) METHOD FOR DETERMINING BORON IN A FERROBOR ALLOY

1one

Изобретение относитс  к анали (Тической химии, а именно к способам анализа боросодержащих материалов. . Известен способ определени  бора в материалах, содержащих железо , еключаю1Дий титриметрическое определение бора в присутствии железа , закомплексованного ЭДТА lj .The invention relates to the analysis of (Ticchemical chemistry, in particular, to methods for the analysis of boron-containing materials. The method of determination of boron in materials containing iron is known, which means: 1) titrimetric determination of boron in the complex of iron complexed with EDTA lj.

Однако известный способ характеризуетс  невысокой точностью в присутствии более чем 20-кратного количества железа и избыток введенной ЭДТА мешает определению бора.However, the known method is characterized by low accuracy in the presence of more than 20 times the amount of iron and an excess of injected EDTA interferes with the determination of boron.

Наиболее близким по технической сущности и достигаемому результату к изобретению  вл етс  способ определени  бора в сплаве Ферробор, включающий растворение анализируемого образца в растворе сол ной кислоты при кип чении, отделение железа на хроматографической колонке, заполненной катионитом СБС в Н фОрме, и последующее титриметрическое определение борной кислоты l2j .The closest in technical essence and the achieved result to the invention is a method for determining boron in a Ferrobor alloy, including dissolving an analyzed sample in a solution of hydrochloric acid during boiling, separation of iron on a chromatographic column filled with SBS cation in H form, and subsequent titrimetric determination of boron acids l2j.

Однако известный способ длителен .However, the known method is long lasting.

Цель изобретени  - ускорение анализа.The purpose of the invention is to accelerate the analysis.

Поставленна  цель достигаетс  тем, что согласно способу определени  бора в сплаве ферробор, включающем растворение исследуемого образ ца в растворе сол ной кислоты при This goal is achieved by the fact that according to the method for determining boron in a ferrobor alloy, including the dissolution of the test sample in a solution of hydrochloric acid at

10 кип чении , отделение железа на хроматографической колонке, запол-. ненной сорбентом, и последующее титриметрическое определение борной кислоты,растворение образца осу15 ществл ют в присутствии перекиси водорода и в качестве сорбента используют порошок фторопласта, обрабо-. танный раствором хлорида триоктиламмони  в нитробензоле.10 boiling, separation of iron on a chromatographic column, fill-. sorbent, and the subsequent titrimetric determination of boric acid, the dissolution of the sample was carried out in the presence of hydrogen peroxide, and fluoroplastic powder was used as a sorbent. solution of trioctylammonium chloride in nitrobenzene.

2020

При этом, с целью повышени  полноты разделени  железа и бора, используют 8,0-9,0 М сол ную кисло|ту .In this case, in order to increase the completeness of the separation of iron and boron, 8.0-9.0 M hydrochloric acid is used.
