In this research,[potassium carbonate](K2CO3) aquatic solution] reinforcement by glutamic sour salt utilized [to][capturing][carbon]dioxide (CO2) from Gaseous fuel] in a stuffed absorber pillar at room temperature and at atmospheric pressure. Effect of glutamic sour salt concentrations on the CO2 absorption rates into carbonate solutions and glutamic acid salt were investigated. The outcome exhibit that the interaction of CO2 with K2CO3 aquatic solution promoted by glutamic acid salt was second-order and the rate constant (k2) was calculated from the experiments. The interaction of CO2 with glutamic sour salt was a depiction utilized zwitterionic self-acting. The aggregate interaction pragmatic stationary (kov) robustly augmentation with the augmentation of glutamic sour salt concentricity based on the pseudo-first-arrange regime.
The potential of pretreated sugarcane bagasse (SCB) as a low-cost and renewable source to yield activated carbon (AC) for chromate CrO42− removal from an aqueous solution has been investigated. Raw sugarcane bagasse was pretreated with H2SO4, H3PO4, HCl, HNO3, KOH, NaOH, or ZnCl2 before carbonization at 700 °C. Only pretreatments with H2SO4 and KOH yield clean AC powders, while the other powders still contain non-carbonaceous components. The point of zero charge for ACs obtained from SCB pretreated with H2SO4 and KOH is 7.71 and 2.62, respectively. Batch equilibrium studies show that the most effective conditions for chromate removal are a low pH (i.e., below 3) where >96% of the chromate is removed from the aqueous solution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
