| 成果简介 | NOVELTY - Composition comprises 22.8 grams of cenosphere (silicon dioxide, aluminum oxide, iron(III) oxide, titanium dioxide) as the primary material (76 wt.%), 1.8 grams of calcium carbonate (CaCO3) (6wt.%), 1.8 grams of sodium carbonate (Na2CO3) (6 wt.%), 1.2 grams of boric acid (H3BO3) (4wt.%), 2.4 grams of sodium metasilicate (Na2SiO3) (8wt.%), where the total weight of the membrane composition is 30 grams. USE - Composition for preparation of cenosphere-based ceramic membrane for efficient separation of methylene blue dye from aqueous solutions. ADVANTAGE - The composition utilizes waste cenospheres, a byproduct from thermal power plants, which provides an environmentally friendly and sustainable approach to membrane fabrication. By utilizing waste cenospheres, the process supports eco-friendly practices by recycling industrial byproducts into functional materials for practical applications, contributing to sustainability efforts. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing cenosphere-based ceramic membrane, which involves milling raw cenospheres (22.8gm) to reduce their particle size from an average of 1.717 µm to 0.719 µm using a ball milling process, mixing cenospheres with calcium carbonate (1.8gm), sodium carbonate (1.8gm), boric acid(1.2gm), and sodium metasilicate(2.4gm) in the proportions specified, thoroughly grinding the mixture in a mortar with incremental additions of a binder (Na2SiO3) and, water is added gradually, drop by drop, as per the requirements for 90 minutes, creating a homogeneous composition, placing homogeneous composition onto a metallic disc with a diameter of 6 cm, which is located within a metallic mould, mould is closed and subjected to a hydraulic press at a pressure of 150 kgf/cm2 for 10 minutes to form a green membrane, this green membrane is left at room temperature for the next 15 hours, subsequently, drying the green membrane at 50°C for 6 hours in an oven, gradually raising the temperature to 800°C at a rate of 100°C/hour and maintaining the final temperature for 8 hours in a muffle furnace, alternating sintering temperatures between 600°C and 900°C, optimizing the membrane's properties at 700°C for achieving high porosity and permeability, the resulting ceramic membrane obtained from this process possesses a diameter of 6 cm and an average thickness of 0.56 cm. DESCRIPTION OF DRAWING(S) - The drawing illustrates the size reduction of the cenosphere utilizing a planetary ball mill. |
