Corrigendum to "Green synthesis of reusable super-paramagnetic diatomite for aqueous nickel (II) removal" [J. Colloid Interface Sci. 582(Part B) (2021) 1179-1190].

Adsorption is an effective method for treating wastewater containing nickel due to its minimal equipment requirements and flexible operation. Therefore, an environmental friendly, inexpensive, efficient and recyclable adsorbent is needed. In this work, a reusable dual-functional super-paramagnetic adsorbent was prepared by combining APTES (3-Aminopropyltriethoxysilane) and EDTA (ethylenediaminetetraacetic acid disodium) with magnetic diatomite for the removal of Ni 2+242+2+2+2+2+2+
