| Summary: | Worldwide industrialisation and agriculture activities have led to
a serious problem of environmental pollution due to the discharge
of toxic contaminants in the watercourse and surroundings. When
disposed in concentrations beyond the maximum limit, heavy metals
can be a source of contamination to the environment. To monitor
the level of contamination, electrochemical sensors can be utilised
for qualitative and quantitative measures. They are known to be
highly selective, less time consuming and lightweight. The portability
of the sensors allows the measurement to be carried out onsite to
ensure the environmental requirements are monitored. On the other
hand, ion-imprinted polymers (IIPs) are developed to mimic the
characteristics of the specific analyte for detection and overcome
the limitations of natural biorecognition elements such as protein,
enzyme and antibodies. Due to the growing interest in IIP application
for heavy metals detection, a comprehensive review on the topic
covering recent works, challenges and gaps in this area is required. In
this mapping study, data from selected studies were extracted,
organised, and categorised by implementing a systematic mapping
process. From 340 studies, a total of 51 studies were included after
the two-step screening phase, and data obtained were extracted and
mapped under four classification schemes. One research question
and two sub-questions were addressed with the data extracted from
all included studies. The sub-questions derived from the main
research question are on the surface modifications of the working
electrode of the sensors and their area of applications. The research
gaps were identified and addressed with several recommendations
for further development in the area related to the application of ionimprinted
polymers for heavy metals detection. |
