“…The purified coir was used to sorb dyes from wastewater using a down-flow hanging sponge reactor. The sorption of the dye followed the Langmuir isotherm model, with a maximum sorption of 303 pt/Co/g at 30 °C, suggesting that the purified coir is suitable for the industrial-scale removal of dyes in dye effluents (Nguyet et al 2020).…”

The global production of coconut, mainly for food and oil production, exceeds 62 million tonnes per annum. Large quantities of coconut husk remain unutilized after industrial processing, giving rise to environmental problems. This fails to exploit the potential presented by the extraction of coir, which could have numerous applications. Traditional products such as textiles, mats, and brushes made from coir are increasingly being joined by new, high-value, non-traditional uses. This review article summarizes new fields of application for coir as reinforcing fibers in binderless fiberboards, natural fiber composites, construction materials, solid biofuels, and an absorbent for heavy metals and toxic materials. The use of coir in these new fields will reduce waste and increase sustainability.

“…As a result, alternative treatment had been investigated for the removal of emerging pollutant including membrane, microbial degradation, and adsorption [4][5][6][7]. Among those methods, adsorption technique has some advantages to eliminate the BPA such as being efficient treatment, allows reaching a good removal percentage, insensitivity, low operating cost and easy application [8][9][10][11]. This method is a process that involved physical/chemical forces between adsorbent and dissolved molecule in adsorbate.…”

Bispheol A (BPA) is one of the new emerging pollutants that frequently utilized in many industries. BPA is a chemical that indisputable can mimic human estrogen and disrupt the endocrine system. Thus, two low-cost adsorbents (oil palm trunk and palm shell) with various physicochemical parameters were analyzed for the removal of BPA. The most favorable pH for adsorption was found to be pH 3 (75% and 77%), the adsorbent dosage was 0.1 g (76% and 78%), while temperature was 25oC (76% and 78%) and agitation speed was 150 rpm (77% and 77%) for both oil palm trunk and palm shell. It was found that the best correlation with the experimental data of BPA adsorption was the Langmuir isotherm model, while the kinetic study could be well described with the pseudo-second-order model. The Fourier Transform Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM), Brunauer–Emmett–Teller (BET) were carried out to understand the functional groups, morphology, and surface area of oil palm trunk and palm shell on adsorption of BPA.

The adsorbent for both cationic and anionic dye based on cellulose and polyaniline was prepared.Cellulose was puri ed from sugarcane bagasse through removal of hemicellulose and lignin. Aniline was polymerized in emulsion state in the presence of cellulose and ammonium persulfate as initiator. The FTIR spectroscopy, SEM observation and determination of porosity con rmed that polyaniline was grafted on the surface of cellulose ber to form cellulose-graft-polyaniline with high porosity. Polyaniline acted as adsorption sites for both cationic dye (methylene blue) and anionic dye (methyl orange). The adsorption on the surface of cellulose-graft-polyaniline followed the Langmuir model, suggesting that the adsorption sites on its surface was uniform. The extent of adsorbing capacity of cellulose-graftpolyaniline toward methylene blue and methyl orange was 1.57 and 0.75 mmol/g, respectively. These values con rmed that cellulose-graft-polyaniline was an e cient adsorbent for both cationic and anionic dyes. The adsorption of either cationic or anionic dye in a mixture solution did not restrain each other.Cellulose-graft-polyaniline was expected to have potential application in practical.
