چکیده
Environmental pollution increases along with industrial developments, one of which is copper (Cu) heavy metal waste. In this research, banana peel as adsorbent was carbonized at 350℃. Then chemically activated ZnCl2 and KMnO4. Biopolymer pellets without carbon were in the form white gel-like beads, KMnO4 0.5 g dark gray, 1 light gray. SEM results showed that pores larger than g. The mechanical strength best percentage biopolymer 6%, while 0,5 2%. worked well removal (II) pH 6 concentration absorbed 3.03 ppm. Meanwhile 5 3.675

Defluoridation of water by activated carbon prepared from banana (Musa paradisiaca) peel and coffee (Coffea arabica) husk
The defluoridation of ground water is regarded as one of the key areas of attention among the universal water community. The present investigation deals with fluoride removal from aqueous solution by thermally activated biosorbents prepared from banana (Musa paradisiaca) peel and coffee (Coffea arabica) husk. Fluoride ion selective electrode was used for the determination and monitoring of fluo...
متن کاملPreparation of Carbon Monoliths from Orange peel for NOx Retention
A series of monoliths are prepared from orange peels and chemically activated with H 3 PO 4 , KOH, ZnCl 2 , and water vapor without a binder. The monoliths were characterized by N 2 adsorption-desorption isotherms at 77 K, Boehm titrations and XPS. Thereafter, monoliths were tested for their ability to establish NO x retention. The results show that the retention capacities of NO x were a funct...
متن کاملChemisorption of Arsine on Activated, Impregnated Carbon Adsorbents
This work discusses an ongoing investigation to characterize microporous adsorbents that affect the removal of arsine from air. One aspect of this work was to develop a test system for generating, transport and detection of arsine gas appropriate for adsorbent breakthrough measurements at part-per-billion (ppb) concentrations. Preliminary adsorption data is provided showing the effect of arsine...
متن کاملBiopolymer-Activated Graphitic Carbon Nitride towards a Sustainable Photocathode Material
Photoelectrochemical (PEC) conversion of solar light into chemical fuels is one of the most promising solutions to the challenge of sustainable energy. Graphitic carbon (IV) nitride polymer (g-CN) is an interesting sustainable photocathode material due to low-cost, visible-light sensitivity, and chemical stability up to 500 °C in air. However, grain boundary effects and limited active sites gre...
