| Abstract: | Recently, Yao et al. [1] published the paper entitled as above.
In Section 3.7 “Sorption dynamics”, the authors mentioned “The
pseudo-first-order equation (Lagergren and Svenska), pseudosecond-
order equation (Ho et al.) and the intra-particle diffusion
models with Eqs. from (3) to (5)” without any citations. A citation
review of the Lagergren rate equation for adsorption reactions has
been presented [2]. The correct reference citing the original Lagergren
paper was first presented by Ho et al. in 1998: “S. Lagergren,
zur theorie der sogenannten adsorption gelöster stoffe, Kungliga
Svenska Vetenskapsakademiens, Handlingar, Band 24, No. 4, (1898)
1–39.” Its English translation is “S. Lagergren, about the theory
of so-called adsorption of soluble substances, Kungliga Svenska
Vetenskapsakademiens, Handlingar, Band 24, No. 4, (1898) 1–39”
and the abbreviation style is “S. Lagergren, zur theorie der sogenannten
adsorption gelöster stoffe, K. Sven, Vetenskapsakad. Handl.,
Band 24, No. 4, (1898) 1–39.” In order to distinguish a kinetic equation
based on the adsorption capacity of a solid from one based on
the concentration of a solution, Lagergren’s first-order rate equation
has been called pseudo-first-order [3]. It is clear that there
is only one author for the pseudo-first-order equation but are not
Lagergren and Svenska. “Svenska” is a word in journal title. The
pseudo-second-order kinetic expression for the adsorption systems
of divalent metal ions using sphagnum peat mosswas presented by
Ho[4] and initial adsorption ratewas also reportedat thesametime.
A modified model has been made in the following years because a
mistake was included in the Ho’s thesis in 1995 [3,5,6]. There are
two authors in the publications for pseudo-second-order equation
but are not “Ho et al.” as authors noticed. In 1963, intra-particle diffusion model was published byWeber and Morris [7]. However,
the intra-particle diffusion model Eq. (5) could not be found in the
paper.
Accuracy of quotations and citations are very important for the
transmission of scientific knowledge. Citation errors reflect very
badly on authors those have published the original ideas already
in journals. Authors should make serious efforts to check the accuracy
of the references cited in their manuscripts as well as read the
original article before quoting it rather than citing from abstracts or
cross-references [8]. I suggest that Yao et al. cite the original or the
most frequently cited papers for the kinetic models to have more
accuracy and details of information about kinetic expression. |
