The effectiveness of orange peel in adsorbing Acid violet 17 from aqueous solutions has been studied as a function of agitation time, adsorbent dosage, initial dye concentration and pH. The adsorption follows both Langmuir and Freundlich isotherms. The adsorption capacity Q0 was 19.88 mg/g at initial pH 6.3. The equilibrium time was found to be 80 min for(More)
In this paper, we report on the synthesis of nanostructured copper oxide particles by both chemical and biological method. A facile and efficient synthesis of copper oxide nanoparticles was carried out with controlled surface properties via green chemistry approach. The CuO nanoparticles synthesized are monodisperse and versatile and were characterized with(More)
This investigation explains the biosynthesis and characterization of copper oxide nanoparticles from an Indian medicinal plant by an eco-friendly method. The main objective of this study is to synthesize copper oxide nanoparticles from Tabernaemontana divaricate leaves through a green chemistry approach. Highly stable, spherical copper oxide nanoparticles(More)
Copper oxide nanoparticles were synthesized by biological method using aqueous extract of Acalypha indica leaf and characterized by UV-visible spectroscopy, XRD, FT-IR, SEM TEM and EDX analysis. The synthesised particles were highly stable, spherical and particle size was in the range of 26-30 nm. The antimicrobial activity of A.indica mediated copper oxide(More)
Polyalthia longifolia is a lofty evergreen plant, native to India, commonly planted due to its effectiveness in alleviating noise pollution. The has been used in the traditional system of medicine for the treatment of fever, skin diseases, diabetics and hypertension. A number of biologically active compounds have been isolated from the plant. However, its(More)
Diabetes mellitus is one of the most common endocrine diseases characterized by hyperglycemia due to absolute or relative deficiency of insulin. One anti diabetic therapeutic approach is to reduce gastrointestinal glucose production and absorption through the inhibition of alpha amylase enzyme plays a major role in preventing rise in postprandial glucose(More)
Textile industry is predominant in employing dyes and chemicals, cause for environmental degradation and human maladies. Synthetic dyes have an adverse effect on the aquatic ecosystem and their toxic substance has to be removed from the effluent before their exoneration. This research paper aimed, to isolate and screen the competent fungi from textile(More)
The seroprevalence of HSV type 1 and 2 both in HIV positive and negative individuals of south India was studied. A comparative analysis was made to study the IgG and IgM antibodies to both types of HSV and the age and gender based distribution of HSV. IgG antibodies were more in HIV positive patients than the IgM antibodies. HSV-1 was more in HIV negative(More)
The ability of the activated carbon prepared from Eichornia Crassipes to remove Reactive Magenta B and Reactive Turquoise Blue dyes from aqueous solution has been carried out as a function of contact time, dose (0.1-0.60 mg/50ml for Magenta B and 0.25-2.0 mg/50ml for Turquoise Blue), pH (2-10) and concentration (25, 50, 75, 100mg.L). An amount of 0.6 g of(More)
