“…Tolcha et al used the flower of Typha latifolia for the uptake of multiclass pesticide residues from contaminated water. These studies show the removal of diazinon, atrazine, chlorothalonil, ametrine, chlorpyrifos, and dimethametryn pesticides from the wastewater using a batch experiment [48]. Elango and Govindasamy used temple waste flowers for the removal of color from textile dyeing effluent.…”

The disposal of biological waste into water bodies is a major global concern as it leads to water pollution resulting in the loss of plenty of revenue in the cleaning of water bodies. Here, in the present research work, sacred flowers were collected, segregated, sun-dried, and powdered. The dried floral powders (marigold and rose) were characterized by field emission scanning electron microscopy (FESEM), electron diffraction spectroscopy (EDS), Fourier transforms infrared spectroscopy (FT-IR), and X-ray diffraction (XRD). The microscopy revealed the irregular spherical shape of the sheet-like structure whose size varies in microns. The EDS revealed the elemental composition which was dominated by mainly carbon and oxygen. The XRD shows the presence of carbon (10-25ɵ) in the amorphous form and the absence of any crystalline phase in the biosorbents. The FT-IR showed peaks that conformed to the presence of functional groups like -OH and a carbonyl group. The dried powders were used as an economical and eco-friendly biosorbent for the removal of methyl red (MR) dye from the aqueous solutions by batch adsorption study. After 60 minutes of contact time, the marigold powder (MGP) and rose petal powder (RPP) showed decolorization of 61.16% and 56.08% for 2 ppm of MR dye. The kinetic revealed that the dye removal reaction does not follow the pseudo-first-order as well as the pseudo-second-order. The utilization of such waste-based biosorbents will minimize solid waste and also will provide an economical biosorbent for the removal of environmental pollutants.

“…For adsorption, activated carbons are commonly employed due to higher specific surface area, higher stability, and removal efficiency [7], but they are expensive [8]. Therefore, current research practices aim at the preparation of lowcost biosorbents from naturally available biomass [9][10][11][12][13][14][15]. For 2,4-D removal, different biosorbents such as cotton plant ash and char [16], activated carbons from lignocellulosic materials of willow, miscanthus, flax, and hemp shives [17], and water hyacinth [18] were proposed.…”

An acid-thermally modified Merremia vitifolia biosorbent (ATMVB) was used for the removal of 2,4-dichlorophenoxyacetic acid (2,4-D) from its aqueous solution. The characteristics of ATMVB were found to be superior to that of the unmodified Merremia vitifolia biosorbent (UMMVB). Batch biosorption experimental data under the optimal treatment conditions for ATMVB best fitted to a pseudofirst-order kinetics model and Langmuir adsorption isotherm with a defined maximum biosorption capacity. The mechanism of biosorption was explained with two intraparticle diffusion models, namely, Weber and Boyd. The biosorption is exothermic as per the thermodynamic studies. The ATMVB can be considered as a potential biosorbent for the removal of 2,4-D from its aqueous solution.
