“…Thus, results proved that pH has importantly impacted Fe removal as also reported by other scholars [16]. The feed pH may change the nature of the membrane surface charge and pore size, as well as the dissolved metal species and therefore can affect the membrane separation efficiency [17] …”

“…Extraction of metal ions was carried out individually by using their chloride salts, CuCl 2 !2H 2 O, CdCl 2 and HgCl 2 . All experiments were performed at room temperature by using mixture of 50 mg beads and 50 mL metal ion solution (initial concentration: 100 mg/L) in separate flasks which were stirred magnetically for 24 h. The suspensions were brought to the desired pH (3,6,9) by adding NaOH (0.1 M) and HCl (0.1 M). After the adsorption was complete, the mixture was filtered, and the residual metal-ion content in the filtrate was determined by AAS.…”

“…Mostly copper, nickel, arsenic, zinc and chromium have been removed using RO with normally higher than 95% up to 99.5% efficiency, and no clear result has been achieved for RO in previous studies (2). Separation occurs in NF and RO due to solution diffusion as well as sieving, the Donnan effect, dielectric exclusion, and electro-migration, which make them useful in the separation of both charged and uncharged organic solutes (10). Additionally, the feed pH can change the nature of the membrane surface charge and pore size, as well as that of dissolved metal species, and therefore can affect the membrane separation efficiency (10).…”
