Out of 78 number of water samples 17.94% samples were found iron concentration < 0.3 ppm,
21.79% samples with in and 60.02% samples found iron concentration >4 ppm.
The study shows that percentage removal decreases with the increase in initial concentration of
iron (Table 2 and Fig.1). The percentage removal of iron was also recorded maximum at two
hour contact time (Fig. 2). The extent of removal of iron at room temperature by bamboo
charcoal was found highly pH dependent. As pH increases, the extent of removal increases,
reaches a maximum value and then decreases further increased up to optimum pH (Table 3 and
Fig.3).
