Vetiveria zizanioides and Cyperus alternifolius were measured for their ability to decontaminate pig farm wastewater in 50_38.5_23 cm (L_W_H) plastic boxes. These plants were grown in pig farm wastewater with CODCr at 825 mg/L, BOD5 at 500 mg/L, NH3-N at 130 mg/L and TP 23 at mg/L, C. alternifolius and V. zizanioides could cut down those index to 64%, 68%, 20% and 18% respectively by hydraulic ...

Vetiver, a perennial C4 grass, has long been known for its multifarious uses in perfumery, medicine and environmental protection. Two distinct vetiver morphotypes have been identified in India, i.e., A. North Indian type characterized by thick and smooth fast growing roots that produce superior quality of laevorotatory oil; and B. South Indian type with more number of thin and hairy roots that ...

The kinetics of supercritical fluid extraction (SFE) of clove and vetiver oils using carbon dioxide as solvent was studied, in order to establish an efficient method to predict extraction curves on large scale. The mass transfer model of Sovová was used to adjust the experimental SFE data, which were obtained at 100 bar and 35 °C for clove and 200 bar and 40 °C for vetiver, using extraction col...

The properties and photocatalytic performance of anatase nanoparticles of pure TiO₂ and a core-shell structure of TiO₂ on calcined vetiver grass leaves have been compared. Samples were fabricated by sol-gel and heating at 450 °C for 5h.The comparison was based on data for X-ray diffraction(XRD), UV-Vis spectrophotometry, photoluminescence, transmission electron microscopy, specific surface area...

Phytoremediation is limited when heavy metals reduce soil quality and, subsequently, inhibit plant growth. In this study, we evaluated the use of attapulgite and bentonite as amendments in contaminated with multiple metals, to improve phytoremediation capacity Vetiver grass Indian mustard. A 21-day greenhouse study was undertaken, investigate tolerance heavy-metal-contaminated soil, well heavy-...
