Ammonium pyrrolidine dithiocarbamate anchored Symphoricarpus albus biomass for lead(II) removal: Batch and column biosorption study

► S. albus was successfully modified with APDC. ► Biosorbent has higher capacity for lead(II) about 3 fold than natural biosorbent. ► Biosorbent was effectively used in both batch and continuous systems. ► Pseudo-second-order and Langmuir models best described the lead(II) biosorption. ► More than one mechanism was played role in lead(II) biosorption process.
