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

This work is aimed at solving the problem on sorption purification of waste gases from sulfur dioxide on the wastes of phosphoric industry, i.e. thermophosphorus slags (TPhS).The solution of this problem is implemented by the new technical result, which is caused in increasing the depth of treatment by sulfur dioxide.Essential features of the claimed technical solution are the sorption purification of sulfur dioxide from waste gases on sorbent, containing layer of the granular TPhS.The experimental results showed that the highest activity of the sorbent, calcined at 500°C, is manifested at a temperature of sorption of 200 °C.With further increase of the process temperature, the degree of sorption does not change and duration of work of the sorbent is reduced.
