MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202641008910 A) filed by Vignan's Foundation For Science, Technology And Research, Tenali, Andhra Pradesh, on Jan. 29, for 'biosorption of heavy metal using rice husk.'
Inventor(s) include Dr. P. Bangaraiah.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "Nowadays environmental pollution is the major issue in the world. The biosorption of heavy metal from industrial wastewater using rice husk was investigated. The dead biomass of husk was recognized as a potential biosorbent for the removal of zinc. The influence of various parameters such as agitation time, dosage, initial ion concentration and pH were studied in batch process to determine the biosorption capacity of a biosorbent. The optimum agitation time for the biosorption of zinc was 34 minutes, optimum dosage was 1gm, optimum initial ion concentration was 19 mg/l,optimum pH was 4.1.The experimental data were analyzed by using Freudlich and Langmuir isotherm models. The data had better explained by Freundlich isotherm than Langmuir model. The kinetic data were better described by pseudo first order kinetics. The maximum removal of zinc onto the husk biosorbent was 68%.The results revealed that rice husk were found to be suitable for biosorption of zinc from industrial wastewaters."
