Turning an invader into a remediate: A phosphorus-coupled Spartina alterniflora-biochar system for coastal cadmium immobilization and carbon sequestration

Description

Dataset Title: Turning an invader into a remediate: A phosphorus-coupled Spartina alterniflora-biochar system for coastal cadmium immobilization and carbon sequestration Description: This dataset contains the raw experimental data supporting the findings of the manuscript titled "Turning an invader into a remediant: A phosphorus-coupled Spartina alterniflora-biochar system for coastal cadmium immobilization and carbon sequestration". Data Details: Batch adsorption data: Raw kinetic and isotherm data (Cd²⁺ concentrations over time and at equilibrium) for sediment, BC500, BC650, and their composites under different phosphorus (P) concentrations (0, 20, 80 mg L⁻¹). Sediment incubation data: Time-series data of pH, redox potential (Eh), total Cd (T-Cd), available Cd (TA-Cd), available P (AP), and soil enzyme activities over the 56-day incubation period across six treatments. Desorption data: Cumulative Cd desorption amounts, P/Cd molar ratios, and kinetic model fitting parameters from the 56-day oxalic acid extraction experiments. Physicochemical characterization data: SEM, BET, FTIR, and XPS raw files where applicable. Usage Notes: Please refer to the corresponding sections of the manuscript (Sections 2-3) and the Supplementary Information (Texts S1-S23, Tables S1-S36) for detailed experimental protocols and parameter definitions. Data processing and plotting can be performed using Origin or Python (Data can be imported directly into Origin 2024).
