Abstract
Correction for ‘The synthesis of calcium arsenate@iron arsenate coating materials and their application for arsenic-containing wastewater treatment’ by Yang Wang et al., RSC Adv., 2020, 10, 719–723.
The authors regret that there were errors in the Characterization of samples section of the original article, in Section 3.1 on page 720 of the original article. These errors are detailed below.
The sentence beginning, “As is known, the main peaks of scorodite (FeAsO4·2H2O) are located at approximately 30.1°, 27.8°, 16.9° and 10.9°…” should read, “As is known, the main peaks of CaHAsO4 are located at approximately 30.1°, 27.8°, 16.9° and 10.9°, which can be indexed as the (221), (220), (101) and (020) lattice planes of CaHAsO4 (JCPDS no. 18-0288), respectively.”
The sentence beginning, “As is known, the main peaks of scorodite located at approximately 30.8° and 31.7°…” should read, “As is known, the main peaks of Ca3(AsO4)2 located at approximately 30.8° and 31.7°, can be indexed as the (020) and (021) lattice planes of Ca3(AsO4)2 (JCPDS no. 01-0933).”
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
