Seasonal distribution of dissolved copper(II) ions at tropical coastal water: in case of Pulau Perhentian, Terengganu

Seawater samples from Pulau Perhentian, Terengganu were analysed for Cu(II) speciation concentration. Samples were collected during pre- and post-monsoon seasons, in order to measure the concentration of dCu (dissolved Cu) and CuL (Natural Organic Cu(II) Binding Ligands) by using CLE-AdCSV (Compet...
