Eichhornia crassipes (Mart.) Solms (natural or carbonized) as biosorbent to remove pollutants in water

Abstract

The prolific aquatic herb Eichhornia crassipes considered a pest in many countries can cause damage such as obstruction of water flows and impair the locomotion of fishing boats. However, E. crassipes is renewable, inexpensive, and widely available in nature, and its ability to adsorb recalcitrant pollutants with mutagenic and carcinogenic properties, including synthetic dyes and heavy metals, has been extensively studied by the scientific community. This review paper analyzes previous reports concerning the use of E. crassipes (in the natural and carbonized form) as an adsorbent for heavy metal cations and textile dye. The adsorptive capacity of E. crassipes, the best conditions (adsorbent dosage, pH, and temperature) for the removal of these pollutants, the mechanism of adsorption, and the comparison between natural and carbonized forms (advantages and disadvantages) are discussed. All the results revised in this review indicated that the use of E. crassipes (and its carbon derived) as adsorbent is promising and is an excellent material to be applied in the water treatment. It could be used in the actual technologies for the treatment of contaminated water by heavy metals and textile dyes; however, more studies need to be made on scale-up, economy projects, and related issues, to be finally implemented in wastewater treatment plants.

Banana Stem (Musa balbisiana Colla) as Potential Biosorbent to Remove Methylene Blue Dye in Wastewater: Isotherm, Kinetic, Thermodynamic Studies and Its Application

“…Several studies related to biosorption have been carried out using several biosorbents such as pensi shell [18], leaf dregs of lemongrass [19], lemongrass leaves biowaste [20], Eichhornia crassipes (Mart.) Solms [21], microalgae (Chlorella vulgaris) [22], prosopis cineraria [23], green seaweed [24], watermelon [25], cactus peel [26], chia seeds [27], coffee grounds [28], and Terminalia catappa shell [29].…”

Application of Water Hyacinth Biomass (Eichhornia crassipes) as an Adsorbent for Methylene Blue Dye from Aqueous Medium: Kinetic and Isothermal Study

“…The FTIR spectra of the water hyacinth parts are shown in Figure 1b and display bands characteristic of cellulose. The cell wall evidently consists mainly of lignin, hemicellulose, and cellulose (among other elements in a smaller proportion), providing functional groups such as amines, carboxyls, hydroxyls, sulfhydryl, carbonyls, involved in the removal of pollutants from water [41].…”

Penerapan Instalasi Wetland Sebagai Pengolah Limbah Cair Rumah Tangga

“…Sedangkan aroma limbah di wadah akhir sudah tidak ada atau tidak berbau lagi. Pihak lain melaporkan tanaman air dalam kegiatan ini, yakni eceng gondok yang berada di alam menyebabkan obstruksi aliran, tapi dinding selnya terdiri dari lignin, hemiselulosa, dan selulosa memiliki gugus fungsi antara lain NH2 (amina), COOH (karboksil), OH (hidroksil), SH (sulfhydryl), dan C = O (Karbonil) berperan sebagai penghilang bahan berbahaya pada limbah cair (Lima and Asencios, 2021). Konfirmasi dari pihak lain seperti Ubogu et al, (2019) melaporkan hasil uji tanah yang terkontaminasi minyak, menunjukkan pengurang harian dari Total Petroleum Hydrocarbon (TPH) oleh enceng gondok sebanyak 49.20 mg/kg/hari.…”
