Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

A new highly selective, accelerated and simple extraction photometric method for determining gold with MB directly in the organic phase has been elaborated. The developed method is tested on the analysis of production solutions of hydrometallurgical plants, concentrates and rocks without separation of accompanying elements. The developed method of extraction-photometric determination of gold with MB is recommended for the analysis of industrial solutions, waste water, ores, concentrates, rocks and other materials complex in terms of chemical composition without separation of the accompanying elements directly in the organic phase. Key words: photometric method, gold, complex compounds, chloroform, gold extraction.
