Kinetic and isotherm studies of copper(II) adsorption on potassium hydroxide treated kenaf (hibiscus cannabinus L.) fiber / Nur Syafiqah Amir Hanafiah

Kenaf fiber which is a by-product of agricultural is easily available and relatively low cost has been investigated as an adsorbent used to remove copper(II) from aqueous solution. The adsorption of copper(II) by potassium-hydroxide-treated Hibiscus cannabinus L. powder (KHCLP) was investigated unde...
