reaching nanoparticle dimensions ...extraction of silica. Rice husk ash is one of the most silica rich raw materials containing about 90-98% silica (after complete combustion) among the family of other agro wastes. Rice husk is a popular boiler fuel and the ash generated usually creates disposal problems. The chemical process discussed not only provides a solution for ...The aim of this experiment was to extract silica from fly ash for the better utilization of fly ash. Extraction of silica can be done by using sodium meta silicate (Na 2 OSiO 3).From this above experiment

hence then a production …Silica has become a popular material due to its high abundance and many advantages in various fields. This material can be produced synthetically and extracted from nature with resultant advantages in the application of green production.Extraction of silica at pHs of 7 and 10 A 10.0 g sample of CCA was stirred in 60 mL of a 1 N NaOH solution. The solution was stirred for 3 h with constant heating in a covered beaker and filtered using a Whatman No. 41 ashless filter. The obtained residue was cleaned with 100 mL of nanopure water. Silica was extracted using this residue.The present study has been designed to evaluate the extraction of silica from rice paddy (husk ash).
