“…In addition, there is also a more rapid and effective separation of organic compounds from the solution compared to coagulation and the operating costs are lower compared to conventional techniques 27 . In the literature, we have witnessed the application of this method to real cases such as catering water for the removal of colloidal matter; oil in water emulsions from restaurants; and urban, agro-industrial and textile industry wastewater with a high content of organic pollutants and suspended solids 28,29 . Iron electrodes present two mechanisms that explain the in situ formation of two possible coagulants (Fe(OH) 2 and Fe(OH) 3 ).…”

Electrocoagulation is a promising technique for the treatment of wastewater like the produced by the textile industry, which generates large volumes of water containing dyes. Thus, synthetic samples of the textile dye acid black 194 (AB194, CI 22910) were treated by this method using iron anodes at two different initial pH values. Tafel studies in the presence and absence of the dye were performed.The complete removal of AB194 from 1.0 L of solution in a static cell was achieved, at short electrolysis times, applying low-density currents at two different initial pH values.In addition, the operating costs by mass consumed anode, per cubic meter electocoagulated and per TOC unit, were assessed to help determine the most efficient conditions, considering a future application of the method in the industry.

“…In addition to heavy metal ions, ion otation is also commonly used for removing organic and biological pollutants such as oil, triazine herbicides, peruorooctane sulfonate (PFOS) and peruorooctanoate, Rhodamine 6G and sulfonylurea herbicides from wastewater or aqueous solution. [41][42][43][44][45][46][47] Lignin removal research was conducted by Wang et al through ion otation using cetyl dimethyl benzyl ammonium as the surfactant. They found that a fraction of more than 0.95 could be removed by continuous ion otation under the optimum operational conditions.…”

“…Limbah zat warna sintesis umumnya berupa senyawa organik non-biodegradable. Banyak metode yang digunakan untuk menanggulangi limbah tekstil ini antara lain flotasi (Suyasa, 2012), koagulasi (Manurung, 2011), elektrokoagulasi (Zaleschi, L. et al, 2014), flokulasi (Yuliastri, 2010), filtrasi (Rosyida, 2011), oksidasi (Rohmah dkk, 2008), dan adsorpsi (Widjanarko dkk, 2006). Salah satu metode yang banyak digunakan untuk menanggulangi limbah tekstil ini adalah adsorpsi.…”

AbstrakHemiselulosa digunakan sebagai adsorben alternatif untuk adsorpsi Rhodamin B. Penelitian ini bertujuan untuk menentukan kapasitas adsorpsi hemiselulosa terhadap rhodamin B dengan optimasi massa adsorben dan pH larutan. Kapasitas adsorpsi hemiselulosa ditentukan dengan sistem dinamis dengan kecepatan 0,08 mL/menit melalui kolom berdiameter internal 8 mm dan menggunakan persamaan Thomas. Hasil penelitian menunjukkan bahwa banyaknya zat warna Rhodamin B yang teradsorpsi pada adsorben hemiselulosa mengalami peningkatan dengan bertambahnya massa adsorben. Adsorben hemiselulosa dapat menyerap zat warna Rhodamin B paling baik pada massa adsorben 0,5 gram dan pH larutan 7,34, dengan kapasitas adsorben hemiselulosa sebesar 0,047 mg/g. Kata Kunci: Adsorben, hemiselulosa, rhodamin B, adsorpsi. AbstractHemicellulose adsorbents are used as an alternative to the adsorption of the Rhodamin B. This aim of this research is to determine the adsorption capacity of the cellulose toward rhodamine B by optimizing the amount of adsorbent and the pH of the solution. The adsorption capacity of cellulose is determined in a dynamic method with a flow rate of 0.08 mL/minutes through a column (8 mm id) and using the Thomas equation. The results showed that the amount of Rhodamin B adsorbed in the hemicellulose adsorbent increased with increasing adsorbent mass. Hemicellulose adsorbent can absorb Rhodamin B best at 0.5 gram adsorbent mass and solution pH 7.34, with hemicellulose adsorbent capacity of 0.047 mg /g.
