The role of natural organic ligands in dissolved copper (II) distribution at tropical coastal water

The vertical distribution of Cu(II) in dissolved and particulate phases was determined in the seawater at Pulau Redang, Terengganu, in April 2019. Our present results have shown a similar concentration of total dissolved Cu(II) at the upper layer (< 15 m depth) and bottom layer (> 15 m depth)....
