Sweetcorn cob activated carbon (Zea mays saccharata Sturt.) has shown potential as an adsorbent due to its large surface area and abundant active sites, making it effective in adsorbing the dye Rhodamine B. The adsorption capability of sweetcorn cob carbon was enhanced through activation using sodium hydroxide (NaOH). This NaOH activation serves to break the bonds between lignin and cellulose, …
