Kajian Pengaruh Waktu dan pH Optimum dalam Adsorpsi Methyl Violet dan Methylene Blue Menggunakan Abu Daun Bambu

Abstract

Adsorption of methyl violet and methylene blue has been done on using bamboo leaf ash. This research
aims to study the characterization adsorbent by FT-IR spectrophotometry and adsorption with the parameters
interaction time and pH. The concentration of the dye was determined quantitively by UV-Vis
spectrophotometer. FT-IR spectogram of bamboo leaf ash show that typical fingerprint in IR spectrogram of
af asdeobent with Si-O and Al-O groups. The adsorption results showed that optimum methyl violet adsorption
at 12 minutes and pH 11 with adsorption capacity of 22.8738 mg/g and adsorption of optimum methylene blue
at contact time of 8 minutes and pH 11 with adsorption capacity of 17.9989 mg/g
