At the equimolar perchlorate - to - oxide ratio , this decrease is about 115 K. From DTA data , the onset temperature of oxygen evolution decreases abruptly as FeO is added ( Fig . 1 , a ) , as under the effect of a - Fe2O3 .

3 : the distribu- tion ratio at low is independent of the metal concen- tration , then it drops with increasing metal concentra- tion . The molecular weight calculated for the extracted complex also proves that scandium is extracted as ...
