Possibility of degradation of phenylarsonic acid in the presence of ferrihydrite

Retention of phenylarsenicals in soils derived from volcanic materials

“…There are few reports studying the behavior of phenylarsonic acid in soil. Shimamoto and Takahashi [36] found 7-10% of inorganic arsenic in the solution when phenylarsonic acid was sorbed onto ferrihydrite at pH = 12.…”
