Phytoremediation

I am using nitric acid - perchloric acid mixture for the digestion of plants. Is it a good digesting method?

I am looking for a formula used to express MDA in nmol g-fresh weight after using Heath and Parker (1968) 's method of assay.

My textile wastewater had a 9.6 pH but had a lack of DO (DO 0,3-0,5 mg/l). Is that normal?

Plants in phytoremediation work on concentrating specific elements, how do we dispose them safely after the remediation process?

I am working on biosorption of arsenic. I made arsenic stock solution by dissolving 1.320g arsenic trioxide with 4g NaOH and making up the volume to 1000 mL with distilled water. 2% nitric acid was added in the distilled water to preserve the stock solution. The dilutions were further made with 2% nitric acid. But when the biosorbent was added and the solution was agitated, it turned to yellow colour. Could this be due to a possible reaction of biosorbent functional group (mainly proteins) with nitric acid?

Which is a good chelating agent for phytoremediation of heavy metals in soil: Ammonium molybdate or EDTA?

Note: shape or size of particulate matter (and other physical or chemical characteristics) can increase its absorbance by plants?

How to prepare pb and cd chemicals methodology

I am working on Phytoremediation of Aromatic hydrocarbon. Trying to reduce the TPH being more specific PAH from soil.

Brackish groundwater contains TDS of 1,000 - 10,000 ppm

I'm looking for a reference to cite.

I made experiment to measure Thlaspi caerulescen hyperaccumulation in spiked soil with different concentration of (Cd & Zn ), the total weight for the plant is enough to make just one sample to be analyzed. now i have just one reading for each soil treatment, & my adviser said i cant publish the data because i have one reading, i measured the concentration in the soil before and after planting Thlaspi, I also measured Microbiological Activity & Counts for Bacteria , Fungi & Actinomycetes . Is my work is Use less & cant be published?

Is there any link either positive or negative about plants that phytoremediate and those that indicate/accumulate contaminants? Since plants that phytoremediate, especially food crops, can in no way be nutritionally encouraged because of health implication of contaminants that have potential to remediate.

Can anyone provide me with any information?

I learned that clinoptilolite can be used to remove heavy metals from soil; I want to know how to go about it. For instance in mine soils, how can it be used to re-mediate that soil? Any ideas? Do you have experience with this?

I am working with novel plants in which not any prior work has been published yet. There are few evidences and unpublished medicinal uses of these plants. The plants from the same genus' were found to have many medicinal values and traditional usage. I did in vivo anti-inflammatory activity and anti-bacterial activity for one plant, in vivo and in vitro anti-diabetic activity for the second one. Both exhibited good activity. I also did GC-MS analysis and docking studies of the compounds identified by GC-MS analysis. I submitted this work as paper to Journal of ethnopharmacology. The reviewer commented that it is good work but not the description of a traditional medicine and said could not accept it for their journal. I then uploaded it to Planta Medica. They also commented tat the concentrations were irrelevant. But i followed the standard protocols and concentrations for all. Could anyone suggest me which international journal with good impact factor would accept these kind of work?

I would like to know about the plant species that can be used for phytoremediation of Organochlorides (or specifically endusulfan)...

What is the effect of pH on metal (Cr) accumulation by plants with respect to phytoremediation?

I´m more interested on sharing some perspectives about field scale aplication of this technology in the agronomical context.

how we will extract the arsenic from land and by which technology efficiently.

Moscow University Biological Sciences Bulletin, 2007, Vol. 62, No. 4, p. 176–179. http://www.researchgate.net/profile/Sergei_Ostroumov/blog/6643_ToleranceMacrophytes; DOI: 10.3103/S0096392507040074; http://www.scribd.com/doc/45556848; Abstract: Macrophytes are important components of ecosystems and participate in the purification of water, which contributes to the sustainability of water quality. This is especially important in conditions of pollution of water bodies and water streams. Surfactants constitute an important class of pollutants. Therefore, further investigation and clarification of the facts concerning the interaction of plants and various surfactants are necessary. The present paper presents the results of investigations of the effect of various concentrations of aqueous solutions of the anionic surfactant sodium dodecyl sulphate (SDS) on the viability of the aquatic macrophytes, the pondweed Potamogeton crispus L. When the effects of the anionic surfactant sodium dodecyl sulphate on the aquatic macrophytes Potamogeton crispus L. were studied, it was found that the concentrations of 83–133 mg/l caused fragmentation of the stems of plants. The tolerance of the plants to the negative effects of the surfactant was higher in the spring (April) than in the autumn (September).

I am a young scientist working of phytoming of platinum. Kindly share the literature regarding platinum hyperaccumulators available till now.

I am currently working on my dissertation research on phytoremediation and I am looking to talk with someone who has somewhat successfully done wok in this area. If there is anyone out there please contact me via my email address on my page. Thanks

New plant species as a POTENT TOOL TO CLEAN WATER AND TO REMOVE HEAVY METALS: This is the first time the phytoremediation potential of a new wide-spread species of plants was discovered. The plant removed the toxic metals cadmium, lead, copper, zinc (Cd, Pb, Cu, Zn) from water with great efficiency. As a result, water quality improved dramatically with prospect of new technology http://blog.researchgate.net/masterblog/594_New_plant_species_as_a_potent_tool_to_clean_water_and_to_remove_heavy_metals Ostroumov S.A., Shestakova T.V.
