Study-level evidence dataset for agricultural-waste adsorbents in heavy-metal wastewater treatment
Description
This dataset contains the study-level evidence coding used in the manuscript “Are Agricultural-Waste Adsorbents Ready for Heavy-Metal Wastewater Treatment? A Systematic Evidence Audit of Real-Water Validation, Regeneration and Process Readiness.” It includes the locked set of 33 source-verified primary studies and records six application-relevant indicators: authentic-water testing, flow/dynamic/continuous operation, repeated regeneration, quantitative economics, recovery or spent-media/end-use evidence, and multi-metal or complex-matrix testing. The dataset provides the audit trail underlying the manuscript’s prevalence calculations, tables, and evidence-integration analysis. No PRISMA identification, deduplication, screening, or exclusion totals are included because a finalized Scopus/Web of Science export with formal deduplication was not available.
