“…Various adsorbents have been investigated for their performance in removing textile waste dyes. Despite operational drawbacks such as saturation, the adsorbent can be regenerated to be reused in the treatment operation (Widajatno et al, 2022). Fazal et al (2015) provide an example of a textile industry wastewater treatment system, which uses conventional wastewater treatment units with the addition of advanced ozonation and adsorption with granular activated carbon (GAC).…”

Graphene Oxide (GO) based adsorbents have attracted much attention from researchers because there have been many reports that they are effective for removing dyes from aqueous environments. That is because GO has good mechanical, electrical, optical and chemical properties, so graphene and its derivatives, such as graphene oxide, have been used in various applications in the field of environmental management. Modifying GO into nano size is an effort to improve its performance in removing dyes. This review uses a database from Science Direct, Google Scholar and Springer, which was screened using graphene oxide, pigments, adsorption and nano adsorbent. The performance of the nano adsorbent showed quite good results in the removal of dyes. The isotherm model suitable for adsorption varies between Langmuir, Freundlich and Redlich-Peterson isotherms. Pseudo-second-order (PSO) is the best model to explain the adsorption process kinetics. Nano-adsorbent modification can be reused at least five times with a reduced adsorption capacity of 4-8%. Studies related to adsorption with GO-based nano adsorbents show promising results in pollutant removal. Still, aspects such as synthesis method, surface functional groups interaction and dye ions and the stability of synthesis products need to be investigated further.

“…3 Hal ini dapat mengganggu keseimbangan ekosistem sungai salah satunya yaitu terganggunya proses fotosintesis dan penurunan oksigen terlarut. 4 Beberapa teknologi secondary dan tertiary treatment seperti lumpur aktif, 5 moving bed biofilm reactor, 6,7 oksidasi kimia, 8,9 dan adsorpsi 10,11 dapat digunakan untuk mengolah limbah tekstil warna, dengan hasil efisiensi, biaya operasional, dan kemudahan proses yang bervariasi. Salah satu metode yang ditawarkan berupa adsorpsi menggunakan karbon aktif yang terbuat dari bahan alternatif yaitu alga.…”

Pengolahan limbah zat warna dapat dilakukan dengan proses adsorpsi, namun mengalami keterbatasan biaya akibat harga adsorben yang mahal. Salah satu bahan baku adsorben potensial yang dapat digunakan adalah mikroalga. Penelitian ini menjelaskan proses pemanfaatan mikroalga dalam bentuk amobil sebagai adsorben untuk penyisihan Reactive Blue 4 (RB4) dan Reactive Red 120 (RR120). Alga yang digunakan berupa alga blooming dari Instalasi Pengolahan Air Limbah (IPAL) Bojongsoang yang dilakukan proses imobilisasi menggunakan silika. Adsorben diuji menggunakan FTIR, pH pzc, BET, dan SEM-EDS. Proses adsorpsi dilakukan dalam sistem batch (variasi perlakuan awal, pH, massa adsorben, dan waktu kontak) dan dalam reaktor kolom (variasi konsentrasi awal). Parameter yang diukur yaitu efisiensi penyisihan, model isoterm (Langmuir/Freundlich), kinetika reaksi (orde satu semu/orde dua semu), dan model kurva breakthrough. Hasil sistem batch menunjukkan kondisi adsorpsi terbaik terjadi menggunakan mikroalga-NaOH saat kondisi larutan pada pH 2 selama 4 jam dengan massa adsorben RB4=2,5 gram dan RR120=2 gram. Efisiensi penyisihan RB4 dan RR120 mencapai 98,58% dan 98,56%. Model isoterm cenderung mengikuti isoterm Langmuir dengan kinetika reaksi orde dua semu. Hasil sistem kolom menunjukkan adanya kenaikan konsentrasi awal memberikan waktu breakthrough yang lebih cepat dan kurva breakthrough paling sesuai dijelaskan menggunakan model Thomas dan Yoon-Nelson. Hasil adsorpsi RB4 dan RR120 menggunakan mikroalga amobil memberikan hasil yang lebih baik bila dibandingkan dengan karbon aktif dalam kondisi yang serupa.
