Carbon 1991, 29, 999−1007. on the adsorption capacity of activated carbons from lignocellulosic precursors
Adsorption Properties of Activated Carbons from Olive Stones 29 Techniques The adsorption of nitrogen at 77 K and of carbon dioxide at 273 K was studied using a Micromeritics Gemini III 2375 instrument. Prior to any measurement, the solids were heated overnight at 548 K under high vacuum (10–4 Torr).
Adsorption of CO2 on Activated Carbons Prepared
Activated carbons were prepared from a lignocellulosic material, African palm shells (Elaeis guineensis), by chemical impregnation of the precursor with solutions of 1–7% w/v Cu(NO3)2 at five different concentrations. These were carbonized in a carbon dioxide atmosphere at 1073 K to obtain different carbons. Their textural properties were characterized by nitrogen and carbon dioxide
The adsorption capacity of activated carbon mainly depends on the porosity and the chemical reactivity of functional groups on its surface. The SEM images in Figure 4 show that activated carbon consists of large and small lumps with many pores and several important properties of cocoa activated carbon are shown in Table 1. FTIR spectroscopy is

The adsorption of salicylic acid, acetaminophen, and methylparaben (pharmaceutical products derived from phenol) on carbons activated with different surface chemistries was carried out. We evaluated the effect of the physicochemical properties of the adsorbent and adsorbates on the adsorption capacity. A study of the adsorbate–adsorbent interactions via immersion calorimetry in the analytes
- Why is polyacrylamide not a polyamide?
- It can be viewed as polyethylene with amide substituents on alternating carbons. Unlike various nylons, polyacrylamide is not a polyamide because the amide groups are not in the polymer backbone. Owing to the presence of the amide (CONH 2) groups, alternating carbon atoms in the backbone are stereogenic (colloquially: chiral).
- What are the different types of polyacrylamide (PAM)?
- Explore the diverse applications of Polyacrylamide (PAM) types – Anionic, Cationic, and Non-ionic. Learn how these polymers are used in water treatment, wastewater treatment, and various industrial processes. Dive into the world of flocculants and polymer chemistry.
- What is an anionic polyacrylamide?
- The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers . Both high- and low-molecular-weight polymers are used as drilling fluid additives.
- What is cationic polyacrylamide (CPAM)?
- Cationic Polyacrylamide (CPAM): CPAM is a linear high-molecular-weight compound known for its affinity and adsorption capabilities due to its active functional groups. It is primarily used for coagulating colloids with negative charges.
