“…Ada beberapa penyebab yang dapat memengaruhi daya adsorben dalam proses adsorpsi terdiri dari jenis adsorbat, waktu kontak, serta ukuran partikel. Semakain kecil ukuran partikel, maka luas permukaannya semakin besar dan daya adsorpsinya semakin kuat [6]. Pada penelitian sebelumnya ukuran partikel dan waktu kontak yang optimum berkisar antara 100-200 mesh, serta waktu kontak optimum selama 30 menit dalam proses difusi dan melekatnya ion logam pada proses adsorpsi [7].…”

Research has been carried out to determine the effectiveness of blood clam (Anadara granosa) shell adsorbents in improving the quality of peat water. Blood clam shells were mashed with variations in particle size of 8 mesh, 50 mesh and 150 mesh, then an adsorption process was carried out with a mass ratio of adsorbent and peat water of 1:10. The physical and chemical parameters tested in this study included turbidity, color, Total Dissolved Solid (TDS), and pH. Based on the test results with a contact time of 12 hours, peat water levels increased for all parameters along with increasing particle size. Meanwhile, within 7 days of contact time, the results of the peat water test experienced a decrease in levels for all parameters along with increasing particle size and was a good optimum contact time in the adsorption process. The results obtained show that for the parameters of turbidity, Total Dissolvesd Solid (TDS), and pH have met the standard set by the Minister of Health of the Republic of Indonesia No. 32 of 2017, only the color parameter does not meet the standard in improving the quality of peat water.

“…Zeolit mempunyai struktur tiga dimensi bentuk kristal yang sangat teratur dengan rongga yang saling berhubungan ke segala arah yang menyebabkan luas permukaan zeolit sangat besar sehingga sangat baik digunakan sebagai adsorben [3]. Kemampuan adsorpsi zeolit alam dapat ditingkatkan secara intensif dengan cara impregnasi menggunakan substansi yang cocok [9]. Permukaan zeolit dapat ditingkatkan dengan cara impregnasi menggunakan logam.…”

Research on phosphate adsorption using natural zeolites which were activated and impregnated with HCl and Mg2 +had been carried out. This study examined the effect of natural zeolite particle size on phosphate ion adsorption. Stages of the study began from sifting zeolites in accordance with the specified size (50/70 mesh, 70/110 mesh and 110/120 mesh), washing, activation and impregnation. Natural zeolite with 110/120 mesh particle size is used to determine the contact time in absorbing phosphate ions. Natural zeolite can absorb phosphate as much as 8.53 mg / l or 85.3% with a contact time of 35 minutes. The variation of the adsorption on the natural zeolite particle size is carried out to get the effect of the natural zeolite particle size on the adsorption of phosphate ions. Phosphate ions which are absorbed by zeolites are analyzed using a UV-Vis spectrophotometer. The highest absorption efficiency (99.26%) was obtained for natural zeolite particle size 110/120 mesh. The natural zeolite adsorption isotherm model of the phosphate ion is tested with the Freundlich and Langmuir equations. Based on the data obtained, the isotherm model suitable for this study is Freundlich with a value of R2 = 0.985.

Modification of Activated Carbon from Rice Husk using Hexadecyltrimethylammonium Bromide (HDTMA-Br) Surfactant and ZnCl2 activator and Microwaves for Nitrate Ion Adsorption

Surfactant Modified Activated Carbon (SMAC) is a surfactant-modified activated carbon product. The surfactant used in this study was the cationic surfactant Hexadecyltrimethylammonium Bromide (HDTMA-Br). These surfactants can change the activated carbon's surface to be positively charged due to the presence of the surfactant hydrophilic groups. This SMAC is more selective in absorbing anions, which in this study is for the adsorption of nitrate anions. This research aims to prepare a new material that is superior to activated carbon in absorbing nitrate anions. This research was conducted in several stages. In the first stage, rice husk was carbonized through pyrolysis at 300°C for 10 minutes. In the second stage, carbon was activated using 30% ZnCl2 and microwaves for 5 minutes and 400 W. The third stage was modifying activated carbon by contacting or adsorbing HDTMA-Br on activated carbon. The concentration of HDTMA-Br varied at 200-400 ppm and the adsorption time was 3-7 hours. The success of the modification was measured by the efficiency of HDTMA-Br in modifying activated carbon. This is supported by the results of the characterization of FTIR, GSA, SEM, and thermodynamic parameters. The resulting SMAC was applied for the adsorption of nitrate anions, and the results were compared to carbon and activated carbon. The results indicate that the best SMAC is formed at an optimum concentration of 300 ppm, within 4 hours, with an adsorption efficiency of 97.345%. The characterization results also show that SMAC has been formed, as evidenced by the presence of a peak at a wavenumber of about 1500 cm-1, a C-N group derived from N(CH3)3 in the HDTMA-Br surfactant structure. The SMAC spectra also appeared weak peaks at the wave number 2918 cm-1, which indicated the CH2-R group stretching from the HDTMA-Br surfactant. SEM image shows that HDTMA-Br has covered the pores of activated carbon. Meanwhile, the SMAC surface area is lower than that of activated carbon. Thermodynamic parameters indicate that HDTMA-Br interacts physically with activated carbon. The adsorption capacity of nitrate anion by SMAC is 3,638 mg/g, higher than carbon and activated carbon.
