Chemical Activation of an Activated Carbon Prepared from Coffee Residue

Preparation and characterization of sucrose-based microporous carbons for increasing hydrogen storage

“…Activation is generally performed with a chemical reagent to enhance the specific surface area and micropore volume of carbon materials. Chemical activation can increase the microporosity of carbons by erosion of the carbon surface [26][27][28].…”

“…Activation is generally performed with a chemical reagent to enhance the specific surface area and micropore volume of carbon materials. Chemical activation can increase the microporosity of carbons by erosion of the carbon surface [26][27][28].In this study, sucrose-based microporous activated carbons are prepared by chemical activation using potassium hydroxide. The effect of the activation temperature on the specific surface area and microporosity of the carbon materials and hydrogen storage capacity at 77 K and 1 bar is discussed.…”

Factor Affecting Textile Dye Removal Using Adsorbent From Activated Carbon: A Review

“…Various studied by researchers has been conduct on raw and activated carbon agricultural waste [50] such as sugarcane bagasse [8,18,[50][51][52][53][54][55], olive stone [56], date pits [20],langsat peel [34], apple waste [42], macadamia shell [57], rice husk [52], orange peel [58], prosopis juliflora plant [59], bamboo [60], corncob [41], coffee residue [61], pomegranate peel [1,32], coconut shell [11,62] etc. These agricultural waste have been investigated for various dye removal from aqueous solution such as basic dye [15,[63][64], direct dye [11], benzidine-based dye [6], reactive dye [47,65] and others.…”

The potential for the use of waste products from a variety of sectors in water treatment processes

“…Metal removal has been achieved using both coffee grounds and tea leaf wastes (Djati Utomo and Hunter, 2010). Phenol removal has also been successful with activated carbon prepared from coffee residue (Lamine et al, 2014). Wang et al (2014) reported a NO 3 --N removal efficiency of almost 52% using green tea extract.…”
