The authors wish to make a change to the published paper [1]. In the original manuscript, there are mistakes in the headers of columns six and seven in Table 1. The corrected Table 1 is presented below.
Table 1.
Accuracy, precision, limit of detection and limit of quantification of colistin A, colistin B and polymyxin B from different kinds of water samples spiked with the mixture of target analytes (10 µg L−1 for each) after MISPE treatment.

The authors apologize for any inconvenience caused and the change does not affect the scientific results. The manuscript will be updated, and the original will remain online on the article webpage at https://www.mdpi.com/2073-4360/12/1/131.
