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.
The influence of concentration, solution pH, and temperature on the adsorption of a cationic surfactant on activated bentonite is studied. It is shown that changes in the chemical properties of the surface of the mineral promote variations in its sorption characteristics with respect to methylene blue and do not affect significantly the sorption of phenol.
