The viability of base-treated juniper fiber (BTJF) media for removing toxic heavy metals (Cd2+, Cu2+, Pb2+, Zn+) in stormwater runoff was investigated. The sorption ability ofthe BTJF for all metals was much higher than that of untreated juniper. The affinity sequence of both materials, BTJF and untreated juniper, was Pb > Cu > Zn:,. Cd. This order is explained by the hydrolysis constants for e...

This study uses a setup involving scanning electron microscopy (SEM) to examine the infiltration behaviour and mechanism of formation filter cake from sand-modified bentonite slurry. We began by determining whether can be formed using water–bentonite slurry in samples fine, medium, coarse sand (Series 1). Water–bentonite–sand slurries with different mass ratios fine (B:S) were subsequently test...
