Chrysanthemum indicum microparticles on removal of hazardous Congo red dye using response surface methodology

Abstract

Biomass-derived adsorbents have been intensively studied due to their competence in reducing pollutants with conventional methods. Flowers are used as source in medicine, cosmetics and even as adsorbents for pollutant abatement. In this study, the microparticles from Chrysanthemum indicum were used as adsorbent for reducing the Congo red dye concentration from synthetic solution. Batch trials were evaluated to understand the influence of factors and optimization was carried out using central composite design. Maximum reduction (84.1%) achieved under the optimized settings of pH (1.0), adsorbent dose (300 ppm), stirring speed (150 rpm), and contact time (75 min) at initial dye concentration (150 ppm at 30 °C). Microparticle size ensured with surface morphology of the adsorbent using electron microscopy and functional groups was studied using infrared spectroscopy techniques, respectively. Regression coefficient (R 2) value was obtained as 0.956 which indicates that the predicted values were in good agreement with their corresponding experimental values for the Congo red dye adsorption. Based on the investigation, it is inferred that the Chrysanthemum indicum flower has the potential for Congo red dye reduction from aqueous solution.

Screening of plant species for phytoremediation of synthetic textile dye wastewater

“…Trachyspermum ammi Ajwain Apiaceae [34] Bryophyllum fedtschenkoi Lavender scallops Crassulaceae [35] Chrysanthemum indicum Guldaudi Asteraceae [36] Tagetes erecta Marigold Asteraceae [31] Hibiscus rosa-sinensis Chiana rose Malvaceae [37] Catharanthus roseus Periwinkle Apocynaceae [33]…”

“…There is no research work based on textile dye removal by Trachyspermum ammi (T. ammi), Tagetes erecta (T. erecta), Hibiscus rosa-sinensis (H. rosa-sinensis), Chrysanthemum indicum (C. indicum), Bryophyllum fedtschenkoi (B. fedtschenkoi), Catharanthus roseus (C. roseus). In literature, these plant species reported for their potential of heavy metal remediation in different studies [30][31][32][33][34][35][36][37] where these plants have an e cient root system and plants do not affect the food chain. Due to less explore of these ornamental plants for dyes removal, this research study focussed the ability of screened plants for decolorization of Methylene Blue and Congo Red dyes.…”

Screening the six plant species for phytoremediation of synthetic textile dye waste water

“…Comparison of Chrysanthemum indium plant is exhibited with Dahlia and Calendula for the removal of the Cr metal from the soil [32]. C. indium plant is used to remove CR dye in which ower of the plant act as an adsorbent to remove the CR dye [33]. Bryophyllum pinnatum indicated the tendency to remove Co, Pb, Zn from the soil in comparison with other plants such as Telfaira occidentalis, Talinum triangular.…”

Synthesis of adsorbents from wheat hulls, extracted cellulose and modified with Cetyl trimethyl ammonium chloride to remove Congo Red in aqueous solution

“…To remove Congo Red in aqueous solution, live and dead biomasses have been modified, such as: Funalia trogii with iminodiacetic acid and triethylenetetramine. (Bayramoglu & Arica, 2018), lignina aminada y salinizada (An et al, 2020), microparticles of Chrysanthemum indicum (Chukki et al, 2018) andTrichoderma (Argumedo-Delira et al, 2021).…”
