High surface area activated carbon prepared from cassava peel by chemical activation

Surface properties of activated carbon prepared from wastes

“…According to the IUPAC classification, the Type I isotherm is associated with microporous structures. [6] The major uptake occurs at relative pressure less than 0.1. The initial part of the isotherm represents micropore filling, and a low slope of the plateau indicates multilayer adsorption on the external surface.…”

“…[1] Of the various porous materials, activated carbon is the most widely used for environmental applications such as gas separation, solvent recovery and water purification because of its high specific surface area and pore volume. [2] Many agricultural byproducts and animal wastes have been used as sources for activated carbon, such as date stones, [3] corn cob, [4] pistachio shells, [5] cassava peel, [6] olive cake, [7] broiler manure, [8] cow dung [9] and cattle manure. [10] There are two processes for preparation of activated carbon: physical and chemical activation.…”

Pore structure of activated carbon prepared from hazelnut bagasse by chemical activation

“…This phenomenon results in widening of the spaces between carbon atomic layers and increase in the total pore volume and surface area. [1] …”

“…The main application of this adsorbent is separation and purification of gaseous and liquid phase mixtures. [1] Adsorption is one of the most effective processes of advanced wastewater treatment, which reduces hazardous traces of organic and inorganic wastes left in effluents after the conventional treatment. Activated carbons have the advantage of exhibiting a high adsorption capacity for pollutants due to their high specific area, adequate pore size distribution and relatively high mechanical strength.…”

STUDY PORE CHARACTERIZATION OF γ-ALUMINA – ACTIVATED CARBON COMPOSITE MADE OF CASSAVA PEELS (Manihot esculenta Cranz)

“…Berbagai bahan baku dari limbah pertanian dapat digunakan untuk menghasilkan arang aktif yaitu bahan yang mengandung karbon, antara lain berbagai jenis kayu, serbuk gergaji, kulit atau biji buah-buahan, tongkol jagung, tempurung kelapa, sekam padi dan lain-lain (Nailasa, 2013). Limbah kulit singkong dapat dibuat menjadi karbon aktif (Sudaryanto, et al, 2006). Singkong (Manihot esculenta Cranz) yang sering dikenal sebagai ketela pohon merupakan pohon tahunan tropika dan subtropika dari keluarga Euphorbiaceae.…”
