Determination of sedimentation rates and absorption coefficient of insoluble metal carbonates

Abstract

Studies on the sedimentation rates of insoluble metal carbonates showed that Zn²⁺ has a higher sedimentation rate of 5.10x10^-2 s^-1 while Ni²⁺ has the lowest sedimentation rates of 1.10 x10^-3. The rate of sedimentation of the metal carbonates decreased in the order: Zn²⁺ > Cd²⁺ > Cu²⁺ > Co²⁺ > Ni²⁺. The order showed a decrease in the density of the carbonates and also correlated with the decrease in the mass (and particle) absorption coefficient of the metal carbonates.
