Japanese Knotweed Biochar Dissolved Organic Matter from Seven Extraction Methods

A 674.9 KB dataset on figshare, last updated April 15, 2026, by Jing Qiu. It investigates dissolved organic matter released from Japanese knotweed-derived biochar produced at 500 °C. The data compares seven extraction methods, measuring dissolved organic carbon, aromaticity, molecular weight, and fluorescence components.

Use Cases

• Compare the influence of extraction methods on dissolved organic carbon release based on the seven tested procedures.
• Analyze the relationship between extraction method and BDOM aromaticity based on SUVA254 measurements.
• Model the molecular weight characteristics of BDOM based on E2/E3 ratio data.
• Identify and classify fluorescence components in BDOM based on the four distinct types described.
• Assess environmental implications for carbon dynamics based on the quantity and composition of released BDOM.

Strengths

• Directly compares seven distinct extraction methods, providing a systematic framework.
• Includes specific quantitative measurements for DOC release (5-183 mg L⁻¹), aromaticity (SUVA254: 1.8–5.3), and molecular weight indicators.
• Identifies four distinct fluorescence components (C1-C4) linked to different extraction conditions.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is relatively small (674.9 KB), indicating limited scope.
