Conversion of bare corn cobs waste into sustainable and ecofriendly nanobiosorbent for effective removal of cationic basic fuchsin and methylene blue dyes from water
: Biochars are commonly employed as examples of sustainable biosorbents with wide and recent interests and applications in several fields including water purification from various toxic pollutants. Nanobiosorbents are mainly fabricated from agricultural, animal and industrial wastes. In the current investigation, bare corn cobs waste (BCCW) was pyrolyzed for 1 h (at 400 o C) to generate a sustainable, low-cost and ecofriendly nanobiosorbent (BCCW-NB) for further implementation as an effective material for removal of cationic basic fuchsin (BF) and methylene blue (MB) dyes from water. A nano-scaled (17 nm) was characterized for the as-prepared nanobiosorbent from the HR-TEM imaging analysis. The influence of several impacting factors (viz. pH, time, dosage, concentration, competing species and temperature) were explored and optimized
