How to Parboil Rice to Remove Arsenic | Healthy Home …
Then, drain the rice and refresh it with cool water. The last step is to simmer the rice on a lower heat until all the water is absorbed. Dr. Manoj Menon and his team of researchers found that parboiling in this manner removes over 50% of the arsenic in brown rice and 74% in white rice. In addition, micronutrient levels remain unchanged.

Review on arsenic removal using biochar-based materials
For alkaline solution, i.e., pH from 7 to 10, removal efficiencies decreased for As (III) and As (V). In contrast, Alam et al. (2018) observed the influence of pH on the sorption of As (III) as well as (V) using C. fistula biochar and found maximum removal of 85% at pH 2 for As (V) and 78% at pH 6 for As (III).
