| Abstract: | When the content of Ga in coal ash was determined by Rhodamine B absorphotometry,silica gel influences the test result severly.Heating is usually adopted to dehydrate and get rid it.The factors to influence dehydration effect are mainly temprature and time,but they have not been in all materials.The influences of temprature and time on dehydration were studied.The best temprature and time of it were decided and did experiments to add and recover the fixed quantity of Ga,under such condition.The recovery is 97.3%. |
