# Some references for f-ring

A commutative ring $R$ is said to be an $f-ring$ if every pure ideal is generated by idempotents. (Recall that the ideal $I$ is said to be pure if for each $a\in I$ there is a $b\in I$ such that $ab = a$.) I am looking for some good references for commutative $f-ring$, are there any?
