Abstract:

The objective of this study was to utilize paper chromatography (PC) as a cost-effective and accessible method to impart fundamental principles of chromatography to undergraduate students in introductory inorganic chemistry courses. The experiments focused on detecting and separating metal ions from various groups in the analytical table. Specifically, the study aimed to educate students on the separation and identification of metal ions, comparing color spots and retention factor values, and understanding the influence of alkalinity during metal ion oxidation. Paper chromatography and planar chromatography share the use of solid, flat stationary phases. In this study, Whatman quantitative grade 41 filter paper was employed as the stationary phase. Minimal sample quantities were utilized for qualitative analysis. Through the use of different eluting agents, PC was employed to separate and identify transition metal ions such as (Fe³⁺& Cr³⁺) in group III, (Pb²⁺& Cu²⁺) in group II, Co²⁺& Ni²⁺in group IV, (Co²⁺& Cu²⁺) in group IV and II, (Cu²⁺& Fe³⁺) in group II and III, and (Mo⁶⁺& W⁶⁺) in group VI, based on their distinct color spots and retention factor (R_f) values. This qualitative investigation enabled undergraduate students to appreciate the efficacy of PC in identifying and separating pairs of metal ions through observation of different color spots and their corresponding R_f values.
