The Original Article was published on 06 November 2021

Correction to: BMC Chem (2021) 15:60 https://doi.org/10.1186/s13065-021-00786-7

Following publication of the original article [1], the author group was incorrectly published with the inclusion of the last author “Grzegorz Boczkaj” who did not approve to be author of the article. Hence, the article was corrected with the following author groups and updated author contribution statement:


Author list: Massoud Kaykhaii, Sayyed Hossein Hashemi, Fariba Andarz, Amin Piri and Ghasem Sargazi.


Authors’ contributions: MK planned the study and wrote the manuscript. SHH co-wrote and updated the manuscript. FA did the practical work. AP did the chemometrics, GS synthesized MOF. All authors read and approved the final manuscript.


The original article has been corrected.
