This study compares the material characteristics and evaluates the Cr(VI) adsorption capacity of biochar derived from a novel byproduct (young durian fruit, YDF), synthesized using two pyrolysis methods (traditional and microwave-assisted). The optimal pyrolysis conditions for porosity were 800 °C and 800 W for 30 min, respectively. The traditional pyrolysis method yielded a very high surface area and pore volume (668 m/g; 0.332 cm/g). XRD patterns and FTIR spectra demonstrated structural and functional group differences, significantly impacting the Cr(VI) removal efficiency in water. pH was a critical factor with optimal adsorption at pH 2.0. The adsorption process reached equilibrium at 180 and 100 min at initial concentrations of 100 and 125 mg/L for biochar synthesized by traditional and microwave-assisted pyrolysis, respectively. The adsorption mechanisms proposed based on modern analytical methods include adsorption-reduction, ion exchange, electrostatic interaction, and surface complexation. Industrial wastewater containing chromium was effectively treated under natural conditions (pH = 5.88; = 129.9 mg/L) using biochar synthesized via microwave, achieving a of 21.41 mg/g. The research results pave the way for new directions in the synthesis and application of biochar in environmental treatment, specifically using young fruit materials and microwave methods.

Introduction: The increasing prevalence of antibiotic-resistant pathogens necessitates the urgent development of new antibacterial agents. Concurrently, synthetic chemistry is moving towards more sustainable practices that minimize environmental impact. This study aims to synthesize 3-aryl-2-benzo[b][1,4]oxazin-2-one derivatives, including the natural product cephalandole A, using a sustainable approach that avoids metal catalysts.

Date processing industries generate substantial quantities of waste, including date seeds, which present disposal challenges and environmental concerns. Traditionally, date seed waste has been discarded through landfilling, open burning, or dumping, leading to soil, air, and water pollution. However, with increasing awareness of environmental sustainability and resource conservation, there is a growing interest in valorizing date seed waste using green extraction technologies and innovative food product development approaches for date seed valorization.

We employed a straightforward microwave-assisted extraction technique to investigate the presence of carbon dots (CDs) in Chinese herbal extracts derived from fructus gardeniae and gardenia charcoal, designated as CDs-1 and CDs-2, respectively. The found CDs exhibited unique photoluminescence with quantum yields of 0.95% for CDs-1 and 1.
