Problem
Treating water containing both inorganic contaminants and persistent organics may require separate process steps. A multifunctional solid must demonstrate activity, stability, recovery, and safety in representative water.
Why it matters
One material capable of immobilization and light-assisted degradation could simplify remediation systems and broaden the treatment range for industrial or municipal effluents.
Approach
The disclosed particulate composite combines carbon with calcium diborate, manganese-magnesium borate, and calcium borate phases and is claimed for direct inorganic-contaminant immobilization and irradiated organic-pollutant degradation.
Who may benefit
Potential beneficiaries include environmental-remediation companies, wastewater laboratories, photocatalyst developers, industrial-water operators, and suppliers of advanced treatment media.
Potential value
The material provides a defined manganese-containing multiphase borate composition, 65–75 nm crystallite size, 100–200 nm median particle size, and two claimed pollutant-treatment modes.
Background
Background
Inorganic ions and organic micropollutants behave differently in water, often requiring adsorption, precipitation, oxidation, or biological treatment in sequence. Multiphase solids may combine binding sites with light-responsive redox activity. To prove utility, however, experiments must quantify contaminant removal, adsorption capacity, transformation kinetics, mineralization, intermediate products, and material leaching. Reuse and separation also influence process cost. The disclosure presents a calcium-, manganese-, magnesium-, boron-, and carbon-containing composite as a candidate for both immobilization and irradiated degradation.
Technology overview
Technology overview
XRD identifies orthorhombic CaB2O4, triclinic MnMgB2O5, and Ca3B2O6, while elemental ranges cover C, Ca, B, Mn, and Mg. The composite has a claimed 65–75 nm average crystallite size, substantially spherical particles and agglomerates, and 100–200 nm Dv50 by HRTEM. Metal salts and boric acid are chelated in water, combined with a polyol to form a gel, dried at 150–300 °C, and calcined at 600–800 °C. Claims cover aqueous immobilization and degradation under actinic light.

Development stage
Development stage
Laboratory synthesis and phase, elemental, and particle characterization are described, with claimed water-treatment methods; contaminant capacity, degradation kinetics, by-products, leaching, and reuse were not established. The development stage was not independently verified.
Commercial opportunity
Commercial opportunity
The composite could be screened for mixed wastewater and remediation systems. Development needs contaminant-specific adsorption and degradation tests, mineralization and by-product analysis, light-energy demand, leaching and ecotoxicity, magnetic or filtration recovery options, repeat-use cycles, competing-solute and real-effluent validation, reactor scale-up, calcination economics, and environmental regulatory review.
