Biochar Adsorbents for Arsenic Removal from Water ...

18.09.2021  Water chemistry, especially pH plays a vital role in the removal of arsenic using biochar adsorbents. For example, using oak wood biochar, greater removal (75%–81%) of As(III) was achieved in between pH 3–7 (Niazi et al. 2018), whereas 84% maximum As(V) was sorbed at pH 6. Except these pH ranges the removals were decreased for both the forms of

Arsenic(V) removal by granular adsorbents made from water ...

20.01.2020  Effect of adsorbent dose on arsenic removal efficiency of GA is shown in Fig. 10. It is noted that the percentage of arsenic removal rose as adsorbent dose increased due to the increase of active sites on adsorbent until the dose of 1.8 g/L, where the maximum percentage of arsenic removal was about 85%. After that, the percentage was stable. The higher mass of
