- •
Basicity has no effect on the structure and morphology of the precipitates in PFS.
- •
The precipitates in PFS prepared by NaClO3 were sodium jarosite.
- •
Na2SO4, NaCl and NaNO3 added into PFS significantly decreased the stability of PFS.
- •
The precipitates in PFS prepared by H2O2 added sodium salt were sodium jarosite.
- •
The existence of sodium ions was an important cause for the instability of PFS.
