TL;DR: FTIR demonstrated that carboxyl and hydroxyl groups were involved in the biosorption of the metal ions in the grafted copolymerization-modified orange peel.

TL;DR: The adsorbent was used to remove Cu (II) from electroplating wastewater and was suitable for repeated use for more than four cycles.

TL;DR: Thermodynamic studies showed the spontaneous and exothermic nature of the adsorption of Cu(2+) by MgOP and KOP, and the pseudo-second-order equation fits the experimental data very well.

TL;DR: In this article, a novel adsorbent was prepared by modifying orange peel with sodium hydroxide and calcium chloride, which was evaluated by infrared spectroscopy (IR), scanning electron microscopy (SEM) and N2-adsorption techniques.

TL;DR: The adsorption process can attain equilibrium within 20 min, and kinetics was found to be best-fit pseudo-second-order equation, and temperature has little effect on the adsorptive capacity of orange peel xanthate.
