“…The removal of metal cation at any pH was much greater than that by hydroxide precipitation. Adsorption of metal cation on adsorbent depends upon the nature of adsorbent surface and the distribution of metal species which distribution also depends on the pH of the solution [12]. The removal efficiency of copper decreased with the decrease of pH, because protons compete with metal ion for the adsorption sites on the adsorbent surface as well as the ion existing decrease of negative charge by association of the functional group with proton.…”

Abstract-Low-cost adsorbent was prepared from volcanic ash of Mount Kelud in Indonesia which erupted in 2014 and remained million cubic of ash. The purpose of this study was to investigate the adsorption capacity of volcano ash to remove Cu(II) in water. Some parameters such as mass of the adsorbent, pH of solution, and shaking time were investigated in order to know the adsorption ability of the adsorbent. FTIR and SEM were utilized in order to know the functional group and surface of adsorbent. The presence of carboxyl and hydroxyl functional groups in this adsorbent were important in the process of adsorption. It was found that pH 6 of solution and 120 minutes of shaking time was a suitable condition for this adsorbent in adsorbing copper ion. Langmuir isotherm adsorption model was fit for this adsorbent and the adsorption capacity for Cu (II) was 82.64 mg/g.

ABSTRAKPenelitian tentang adsorbsi ion Cr(VI) dengan menggunakan adsorben dari limbah padat lumpur aktif industri crumb rubber telah dilakukan dengan metode statis (batch). Sampel yang digunakan adalah limbah padat lumpur aktif industri crumb rubber segar dan lumpur yang dikarbonisasi serta diaktivasi dengan KOH. Parameter yang dipelajari yaitu pH awal larutan, waktu kontak, dan konsentrasi ion Cr(VI). Hasil penelitian menunjukan bahwa limbah padat lumpur aktif industri crumb rubber mengandung silika dan alumina yang tinggi yaitu 49,0% dan 16,5%, sehingga dapat digunakan sebagai adsorben. pH optimum adsorben untuk lumpur diaktivasi yaitu pada pH 1 dan lumpur segar pada pH 2. Waktu kontak optimum yaitu 120 menit dan konsentrasi ion Cr(VI) optimum 70 mg/L untuk masingmasing adsorben. Data sesuai dengan isotherm Langmuir dengan kapasitas serapan maksimum terhadap ion Cr(VI) 2,075 mg/g untuk adsorben lumpur diaktivasi dengan KOH dan 2,232 mg/g untuk adsorben lumpur segar. Kata Kunci: Adsorpsi, limbah lumpur aktif, industri crumb rubber, ion Cr(VI), isotherm Langmuir ABSTRACT Research on ion Cr(VI) adsorption by using adsorbent from waste activated sludge crumb rubber industry has been done with static method (batch

“…As an adsorbent, activated carbon has been often applied in many countries, however, this material is high cost [4]. Some researcher developed an alternative adsorbent material for removal of heavy metals and other contaminants from water such as adsorbent based on drinking water treatment plant sludge [5], adsorbent based on water hyacinth [6], adsorbent based on the ash of volcanic [7].…”

Laundry activities grow rapidly in Indonesia in the recent year, remaining the problem of environmental pollution because of the use of detergent. The purpose of the current study was to investigate the ability of sludge of drinking water treatment plant (DWTP) as adsorbent combined with phytoremediation system to remove chemical oxygen demand (COD), phosphate and surfactant in laundry wastewater. Batch and continuous blow studies were conducted on different variables such as adsorbent mass, contact time, and type of plant for phytoremediation system. The results of the current study show that adsorption combined phytoremediation system could remove COD, phosphate, and surfactant up to 77.5%, 54.3%, and 99.9%, respectively. Based on the results, it means that the adsorption combined phytoremediation system could be considered as an appropriate environmental technology for laundry wastewater treatment in the near future.
