The present study aims to identify the suitable low-cost adsorbent obtained from plant residues viz. potato peel and neem bark. Sorption potential of chemically treated potato peel and neem bark is observed on three different synthetic dyes viz. Methylene Blue (MB), Malachite Green (MG) and Direct Red 81 (DR-81). Selected adsorbents are treated with formaldehyde and sulphuric acid solution separately and consequently four different adsorbents PP and APP, NB and ANB are obtained. The monolayer adsorption capacity of HCHO treated potato peel (PP) for MB, MG, and DR81 is estimated as 47.6 mg/gm, 125 mg/gm and 58.8 mg/gm respectively whereas the monolayer adsorption capacity of HCHO treated neem bark (NB) is obtained as 90.9 mg/gm, 250 mg/gm and 8.40 mg/gm for the same dyes. In case of acid-treated potato peel (APP) the monolayer adsorption capacity for MB, MG and DR-81 are estimated as 41.6 mg/gm, 166 mg/gm and 10.41 mg/gm respectively whereas the adsorption capacity of acid-treated neem bark (ANB) for the same dyes is obtained as 1000 mg/gm, 500mg/gm and 5.71 mg/gm respectively. From the study it was found that NB and ANB performed better than PP and APP for basic dyes, Methylene Blue and Malachite Green whereas for removal of acidic dye, Direct Red 81, formaldehyde-treated potato peel (PP) emerged out as the superior adsorbent. Also, ANB worked remarkably for cationic dyes while PP worked efficiently for anionic dye.
