“…Activation of carbon using acids will produce carbon with greater activity, greater the carbon surface acidity, and good porosity. A chemical activity using HCl aims to make the surface of carbon acidic, so that the adsorption capacity of carbon becomes larger [10]. Activation using HCl can dissolve impurities more than activator NaOH, so that carbon, activated with HCl has more pores formed and the absorption process will be more maximal [11].…”

The results of the first trials show that the TSS content in Batik liquid waste in Pati is quite high at 540.75 mg/L. The study aims to determine the effect of making adsorbents from cassava peel waste which is influenced by the activation of adsorbents on TSS absorption in batik liquid waste. This research method includes the steps of making activated carbon from cassava peel waste, the process of activation of chemical carbon, and the adsorption test of batik liquid waste. Varied variables are for HCl, NaOH and without activators. The results showed a decrease in TSS for activator HCl 282.135 mg/L, NaOH activator 352.375 mg/L and without activator 386.245 mg/L. Based on research, the adsorbent from cassava skin is good for reducing TSS in batik liquid waste. Carbon activation with activator HCl is the most effective in absorbing TSS content in Batik liquid waste.

“…Chemical activation is a process used to increase surface area and pore volumes by introducing acid or base solutions such as H3PO4, H2SO4, NaOH, NaCI, HCI, and ZnCI2 (Bijang et al, 2019). KOH is commonly used activator that can significantly increase the surface area of adsorbents to up to 3000 m 2 /g, with an adsorption capacity of up to 686.6605 mg/g (Utama et al, 2016).…”

The low pH and high metal concentration in acid mine drainage cause environmental problems and affect human health. Adsorption not only removes the pollutants but also increases pH levels. Natural adsorbents have gained attention because of their widespread availability, low cost, and effectiveness. Zalacca peel waste is among the biomass materials showing promise as activated carbon for removing contaminants from acid mine drainage. This study aims to investigate the adsorption capacity of activated carbon from zalacca peel for removing iron and manganese from acid mine drainage. Adsorption studies were conducted in batch experiments using various dosages and contact times. Optimal results were achieved with a dosage of 0.8 grams per 100 mL and contact time of 60 minutes, resulting in 80% removal efficiency for iron and 24% for manganese. The neutralization process occurred post-adsorption, bringing the final pH close to neutral levels, suitable for environmentally safe discharge. Experiment data were fitted to the Freundlich isotherm and pseudo-second order kinetics. FTIR analysis revealed functional groups including C-H, C-O, and C=C was found in the adsorbent. Furthermore, surface area and pore volume experienced slight increases following activation with KOH.
