- METHODS By derivative flame atom absorption method.
- The floc could be eliminated by freezing filtration, absorption method or redistillation method. (Tran.
- An infrared absorption method for the determination of trace sulfur in nickel base superalloys was presented.
- The properties of cured NPER were measured by TGA, DSC and water-boiling absorption method.
- The method seems good but it needs to be tried out.
