Removal of metal ions by adsorption on Al based metal organic frameworks

[Display omitted] •Al-BDC-H, Al-BDC-COOH and Al-BDC-SO3H were synthesized.•Al-MOFs showed with different geometrical (plates, flacks, particles) shapes.•Maximum capacity of Al-BDC-SO3H was 214.9 mg/g for Ag+ and 134.5 mg/g for Cu2+.•After 5 uses of Al-BDC-SO3H, the adsorption capacity lowered by 15.3 – 17.8 %. The electroplating wastewater contains heavy metals at levels that considered to be hazardous to the surrounding environment and is risky to public health. Herein, removal of Cu(II) and Ag(I) ions from the wastewater was studied by using Al-based metal organic frameworks (Al-MOFs). Using different organic linkers, three different Al-MOFs were synthesized and namely Al-BDC-H, Al-BDC-COOH Al-BDC-SO3H. The synthesized Al-MOFs showed with different geometrical shapes represented in plate-like, flacks-like and agglomerated particles structures for Al-BDC-H, Al-BDC-COOH and Al-BDC-SO3H, respectively. The three synthesized Al-MOFs were applied in removal of Ag(I) and Cu (II) ions from wastewater and the adsorption followed the order of Al-BDC-H
