Several low cost biomaterials such as rice husk, sugar cane bagasse, Tulsi Leaf &branches, coconut shell & coir and fly ash were tested for removal of chromium. All the experiments were carried out in batch process. The adsorbent, which had highest chromium (VI) removal, was coconut shell. An influence of chromium concentration, contact time on removal of chromium from effluent was investigated...

Abstract Background: Photocatalytic process is used as a suitable method for o-chlorophenol removal. In this study, the efficiency of a mixture of modified fly ash and TiO2 nanoparticles in photocatalytic removal of o-chlorophenol was evaluated. Methods: After acid washing of fly ash, the absorbent was oxidized with potassium permanganate. ...

Abstract CO 2 capture is a promising approach to aid in the mitigation of global environmental crisis caused by greenhouse gas emissions. The efficiency adsorbents critical success this approach. Sugarcane bagasse fly ash (SBA) was used study as support increase adsorption capacity CaO. physical and chemical characteristics SBA treated with various reagents (HCl, H 3 PO 4 , CH COOH, NaOH, NH O ...

the total coal and lignite consumption of the thermic power plants in turkey is approximately 55 million tons and nearly 15 million tons of fly ash is produced. the remarkable increase in the production of fly ash and its disposal in an environmentally friendly manner is increasingly becoming a matter of global concern. studies for the utilization of fly ash in turkey are necessary to reduce en...

In this study the Sugar cane bagasse ash (SCBA) was characterized for chemical composition, morphological and mineralogical properties. From XRF analysis it found that SCBA has SiO2, Al2O3, Fe2O3 CaO content of 67.25%, 6.37%, 4.21% 13% respectively a very low LOI value 0.34% can be classified as Class F ASTM pozzolan according to C 618-2009. used pozzolanic material after grinding less than 45 ...

This study was carried out to evaluate the effects of blended ash mixture on mechanical properties of concrete. In this study two reference mixtures were used. One of the mixtures was a no-fly ash mixture, and the other mixture contained 35% unblended Class C fly ash. Additional mixtures were composed of three blends of Class C and Class F fly ash while maintaining a total fly ash content of 40...

In this paper, the influence of fly ash content on concrete surface chloride concentration was investigated through periodical tests of surface chloride concentration of concrete by immersing three kinds of concrete specimens in 5.0 wt.% sodium chloride solution. One kind of specimen is common concrete without fly ash, whereas the other two kinds of specimens are mixed with fly ash. The results...

Although the Indian population is largely vegetarian, not much attention has been given to the cultivation of vegetables, as compared to other crops like cereals, pulses and oil seeds. Therefore, the present study was conducted on two leafy vegetables, spinach (Spanacia oleracea L.) and methi (Trigonella foenum graecum L.) commonly grown in Aligarh, as the two popular vegetables of Indian diet....
