Abstract
Titanium dioxide nanopowder was successfully synthesized using a sol-gel technique. The characterization of synthesized Titanium dioxide nanopowder was conducted by XRD, SEM, BET, and FTIR analysis. XRD data states the formation of crystalline anatase Titanium dioxide powder and BET analyser shown a specific surface area of 281.36 m2/g and an average particle size of 21.32 nm. Using the Stereolithography printing technique the cylindrical structured 3D printed model having 35 numbers of channels with 25 mm height, 2 mm pore size diameter and a truncated cone-shaped inlet/outlet section were fabricated. Acrylate photopolymer has been used for the preparation of the 3D devise. This printed channel was further loaded with 4.0 g of Titanium dioxide nanopowder and the inlet/outlet section was packed with glass wool. In order to examine the defluoridation effectiveness of differing fluoride concentrations of 3, 6, 10 mg/L at flow levels of 1 mL/min and 25 °C, a test was performed. The adsorbent loaded 3D printed filtration model developed has demonstrated the defluoridation capability of 4.83±0.365 mg/g. This indicated that the loaded Titanium dioxide had higher defluoridation efficacy than the comparable alternatives. This result provided an indication of usefulness of 3D printed devise for pollutant separation from water.
