Goal and objectives of the project | Built-up analytical procedures, manufacture of home-made sensor and controlled instrument for detection of Hg(II) in trace level in aqueous environment. This creates a premise for self made instruments, meeting reality requirements in our country. |
Main results | Theoretical results:
Applied results: The sensor and instrument were employed to determine Hg(II) in samples of seawater, surface water and wastewater in laboratory as well in the field. Obtained results showed that home-made sensor and instrument can detect Hg(II) in few tens ppt level in different types of water sample. This indicates that the sensor and instrument can be used for effectively fast detection of Hg(II) pollution, supporting to the environmental impact assessment and treatment become further effectiveness. |
Novelty and actuality and scientific meaningfulness of the results | Novelty of the results:
Actuality meaningfulness of the results: The obtained results of the project indicated the method of using sensor and instrument is feasible for detection of Hg(II) at ultra low level on-site. Scientific meaningfulness of the results: The obtained results indicated that home-made sensor provided wide linear range and the limit of detection at ultra trace level can be employed. This reveals that use of electrochemical sensors for on-site detection of heavy metal ions at ultra trace concentrations can be feasible, reduces analysing time and cost. It can support for pollution monitoring activities in water resources. |
