Preparation of Granular Organic Iodine and Selenium Complex Fertilizer Based on Biochar for Biofortification of Parsley.

This study investigates the potential of biochar derived from various biomass sources: apricot kernel (AK), pine sawdust (PS), rice husk (RH), wheat straw (WS), and reed stem (RS) to enhance the yield, nutritional quality, and environmental sustainability of parsley crops. Comprehensive characterization through SEM, EDAX, nitrogen adsorption-desorption isotherms, and FTIR analyses identified AK biochar as the most suitable for further enrichment due to its superior specific surface area (512.3 m/g) and iodine number (51.

Surface Characteristics of Activated Carbon Sorbents Obtained from Biomass for Cleaning Oil-Contaminated Soils.

This study explores the sorption capacity and field application of activated carbons (ACs) derived from plant residues for the remediation of oil-contaminated soils. ACs were prepared from rice husks, reed stalks, pine sawdust and wheat straw using two-stage pyrolysis and chemical activation with potassium hydroxide. The structural and physicochemical properties of these ACs were analyzed using BET surface area measurements, SEM analysis, Raman spectroscopy and FTIR spectroscopy.
