Abstract
Correction for ‘Hydrochar from Sargassum muticum: a sustainable approach for high-capacity removal of Rhodamine B dye’ by D. Spagnuolo et al., RSC Sustain., 2023, 1, 1404–1415, https://doi.org/10.1039/D3SU00134B.
The authors regret that incorrect instrument descriptions were reported in the original manuscript. Firstly, for the hydrothermal carbonization process (Section 2.2), a series 4848 reactor controller (Parr Instrument Company, IL, USA) was used with a 300 mL stainless steel autoclave.
Secondly, the sample morphology was investigated using an FEI QUANTA FEG 450 (Thermo Fisher Scientific, Waltham, MA, USA) scanning electron microscope operating under high vacuum and 20 kV, equipped with energy dispersive X-ray spectrometry (EDAX, Ametek, Tokyo, Japan).
Finally, the authors regret that an error occurred during the preparation of Fig. 6–8, leading to the display of incorrect standard deviations. The updated figures and standard deviations are provided below.
 | ||
| Fig. 1 Adsorbent amount effect on % Rhodamine B removal, sd ≤ 2. | ||
 | ||
| Fig. 2 Time effect on % Rhodamine B removal, sd ≤ 2.4. | ||
 | ||
| Fig. 3 Temperature effect on % Rhodamine B removal, sd ≤ 2.1. | ||
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
