A mass-balance and speciation audit of Langmuir capacities reported for Pb(II) adsorption

Data and code package for an audit of 327 literature Pb(II) adsorption datapoints from 251 studies. Contains the analysis table with a source locator and a description of every capacity value, the extraction table with the blinded re-read fields, the exclusion log, the change log of every value altered by the re-read, the instructions given to the re-read and its raw outputs, the record of the hand check of 30 rows, the authors' check of the rows whose capacity exceeds the ceiling of its isotherm series, the record of the reference checks, a data dictionary, all analysis and figure scripts with a script that re-runs the analysis and compares every result file with the released one, the PHREEQC database used for the numerical cross-check, and package versions and random seeds. See README.md and REPRODUCE.md inside the archive.
