Problem was discussed on the reported equation parameters by Zhou and co-workers [Chinese Journal of Chemical Engineering 25 (10) (2017) 1461-1466] for expressing the meropenem trihydrate solubility in binary (water + acetone and water + tetrahydrofuran) mixtures with the modified Apelblat equation. The reported model parameters do not back-calculate correctly the evaluated solubility as shown in their published work. The reported parameters of the modified Apelblat equation tabulated in Tables 3 and 4 by Zhou and coworkers are in mistake.
