Abstract:Heavy metal ions (HMIs) are very harmful to the ecosystem when they are present in excess of the recommended limits. They are carcinogenic in nature and can cause serious health issues. So, it is important to detect the metal ions quickly and accurately. The metal ions arsenic (As 3+ ), cadmium (Cd 2+ ), chromium (Cr 3+ ), lead (Pb 2+ ), and mercury (Hg 2+ ) are considered to be very toxic among other metal ions. Standard analytical methods like atomic absorption spectroscopy, atomic fluorescence spectroscopy,… Show more
