Electrokinetic (EK)-assisted phytoremediation is one of the methods that have a big potential in enhancing the ability of plant uptake in soils remediation process. This research was conducted to investigate the difference in elemental composition concentration of riverbank soil and the change of pH between pre-and post-phytoremediation under the following condition: 1) control or as-receive sample; 2) Dieffenbachia spp plant with EK system (a pair of EK electrodes connected to a direct current (DC) power supply). After the electrodes were connected to a magnitude of 6V/cm -1 electric field for 4 hours/day, the soil and plant samples were analyzed using and X-ray Fluorescence Spectrometer (XRF) and Scanning Electron Microscope / Energy Dispersive X-ray Spectroscopy (SEM/EDX). The SEM/EDX analysis showed that concentration of elemental composition (Ni, Cu and Zn) in post-phytoremediation plant powder samples had increase while elemental concentrations in the post-phytoremediation soil samples were decreased. XRF analysis presented a variation in soil elemental composition concentration from anode to cathode where the concentration near anode region increased while decreased near the cathode region. A significant changes in soil pH were obtained where the soil pH increase in cathode region while decrease in anode region. The results reveal that the assistance of EK in phytoremediation process has increase the efficiency of plant uptake

River pollution may lead to the cause of death and diseases. The cause of its pollution could due to the mobility of the hazardous or toxic element from the human activities point sources through the groundwater system, and may resulting to aheavy metal migration  into the river stream system. Therefore, an agro-based remediation methods known as Electrokinetic (EK)-assisted phytoremediation was implemented in this research. This technique is versatile and economical in decontaminating heavy metal at the river bank soil area. Hence, this research was focused on investigating the difference in trace elemental concentration in riverbank soil sample between pre- and post-phytoremediation under the electrokinetic influence. The riverbank soil sample was divided into two conditions which are: 1) control (as-received) and 2) EK-assisted phytoremediation by using a tropical plant species known as Dieffenbachia spp. In this study, two stainless steel electrodes were slot in at 5.0 cm depth on both side of this particular plant. A direct current (DC) voltage of 60 V was applied on both cathode and anode electrodes to form a uniform electric field with a magnitude of 6V/cm-1 around the plant root area. This electric field was applied consistently for 4 hours per day. Within a month, the reduction of trace element composition in the riverbank soil sample for pre and post experiment were determined using a non-destructive analytical technique, X-ray Fluorescence Spectroscopy (XRF) and Energy Dispersive X-ray Spectroscopy (EDX) analysis. The analysis show a significant correlation of elemental concentration between pre and post experiment for the soil sample where the soil concentration tend to reduce due to the EK assisted phytoremediation effect.
