Plant toxic and non-toxic nature of organic dyes through adsorption mechanism on cellulose surface

Improved removal of malachite green from aqueous solution using chemically modified cellulose by anhydride

“…The thermodynamic parameters for the 5 adsorption process of MG were given in Table 2 on CPA than that on CEL might indicate stronger interaction between MG and CPA. 15 The absolute value of ΔH 0 on CMA and CPA more than 40 kJ mol −1 meant that the 16 strong interaction was occurred at the adsorbent interface [23,24]. 17 3.5.…”

Malachite green “a cationic dye” and its removal from aqueous solution by adsorption

“…It refers as a substance, usually organic, which is designed to be absorbed or adsorbed by, made to react with, or deposited within a substrate to impart color to that substrate with some degree of permanence (Burkinshaw 2016). Dyes may be classified in several ways (Adegoke and Bello 2015).…”

Use of Cellulosic Materials as Dye Adsorbents — A Prospective Study

“…In most of the articles investigated in the literature, it was observed that experimental data usually adjust better to the pseudo-second order kinetic model because the adsorption process is dependent on both the concentration of the adsorbate with the strength of the adsorbent [48,52,12,51,61,62,63]. …”

“…Given the dependence of the temperature in a range of 30°C to 70°C, the removal of malachite green dye methyl orange using brinjal plant root powder was evaluated in the paper [52]. For the first dye, the authors have observed an increase in the removal capacity by increasing the temperature, while for the second dye, the opposite trend was observed from 40°C.…”

“…The paper [52] also conducted a study of desorption, however, for the malachite green dye and methyl orange on the surface of brinjal plant root powder, and by just using water at 80°C, a recovery of 95% for methyl orange and 10% for malachite green was obtained.…”
