An evaluation of the titrimetric and atomic absorption determination of tin in the certified reference materials, MP-1 and KC-1 / H.F. Steger, Mineral Sciences Division. : M34-20/196E-PDF

“An investigation has been undertaken into the determination of tin in the certified reference materials, MP-1 and KC-1, by the titrimetric and atomic absorption methods. The effect of the nature of the metal used to reduce Sn(IV) to Sn(II) in the titrimetric method has been evaluated. It has been shown that there is no significant difference between the results obtained by the titrimetric method when properly applied and those obtained by the atomic absorption method using the standard additions technique. The mean value for tin in MP-1 and KC-1 by both methods are 2.43% and 0.683% respectively. The value for MP-1 is lower than the recommended value"--Abstract, p. i.
