Relevance of the topic:The article addresses an important environmental issue related to pollution from fireworks.Clear methodology: The experimental procedures, including sample preparation and flame photometry analysis, are well described. Method validation:The study includes an evaluation of the effect of different components on the determination of alkali metals. Practical application:The results are applied to the analysis of commercial fireworks samples. Weaknesses and Suggestions for ImprovementSample size limitations: The study is limited to a relatively small number of commercial samples, which may limit the generalizability of the findings.A larger sample size would provide more robust results.Interferences: While the effect of different components is considered, a more comprehensive study of potential interferences from other elements present in fireworks would be beneficial. Comparison with other methods:Comparing the results obtained by flame photometry with those from other analytical techniques, such as inductively coupled plasma atomic emission spectroscopy (ICP-AES), would help assess the accuracy and precision of the method.Environmental impact: Although the article mentions the environmental impact of fireworks, it would be valuable to quantify the environmental impact of the released metals and propose mitigation measures. Safety considerations:The article should emphasize the safety precautions taken during the handling of fireworks and the chemicals used in the analysis. Conclusions
