Mixing assessment by chemical probe

Journal of Industrial and Engineering Chemistry, 2013

Research papers, short communications, notes, and reviews are published. Research papers should be comprehensive reports containing significant new research data and/or new interpretations of existing data with special emphasis on industrial applications. An abstract of 100-200 words is required. Short communications present scientific or technological information warranting rapid dissemination. Authors should define in the text why the contribution deserves rapid publication. Manuscripts are normally planned to occupy two or three printed journal pages. An abstract limited to 150 words is required. Notes are shorter reports in full on significant work of a more limited scope. Note includes an experimental in details, but not an abstract. Reviews furnish critical surveys of progress limited to the field of industrial and engineering chemistry.

Novel spectrophotometric method for the analysis of ternary mixtures

ERU Research Journal

Though simple, rugged and reliable classical spectrophotometric methods have not proven adequate selectivity in the analysis of ternary mixtures with overlapped spectral data. Recently emerging methods incorporates several steps of mathematical manipulations to resolve the spectral overlap. The work introduces the novel H-point derivative ratio method (HDR) and compares its performance with the recently developed dual wavelength in ratio spectrum (DWRS). The resolution power of the H-point standard additions and the derivative ratio methods-resolve binary mixtures-merge to engender the HDR for the analysis of ternary mixtures. HDR and DWRS methods were applied to resolve the severely overlapped spectral data of the ternary mixture: caffeine, propyphenazone and paracetamol. The latter is the first line antipyretic in COVID19 symptomatic relief. One-way ANOVA statistical analysis proved the absence of significant differences between the analytical results of HDR, DWRS and the reported method. Validation parameters were assessed according to the ICH guidelines. The developed HDR method expressed sensitivity and selectivity potentials for routine analysis of the analytes in their pure powder form, ternary mixture and pharmaceutical formulation without prior extraction or interference from additives.
