Important value index, the Shannon diversity index, and total basal area species were recorded.

Plant diversity of the project area encompasses 49 species of trees, 28 species of shrubs, and 144 species of herbs. A total number of 221 plant species were recorded during the floristic survey in the project area. The study was conducted following the stratified sampling techniques by placing quadrates (1m×1m) for herbs, (5m×5m) for shrubs, and (10m×10m) size for trees in the forest area. The aim of the study was to access the diversity status and ecological status. The present study was carried out in the forest of Kedarnath valley in Garhwal Himalaya. Results of this work are of great importance for the environmental application of GO in the treatment of Co(II) from wastewater and indicated that GO is promising for the natural attenuation of Co(II) and related metal ions from aqueous solution.Įthnobotanical Study and Plant Diversity in the Forest of Kedarnath Valley, Garhwal Himalaya, India

The thermodynamic data calculated from the temperature-dependent uptake isotherms suggests that the uptake of Co(II) on GO is spontaneous and endothermic. The uptake isotherms can be described better by the Langmuir, Freundlich, and D-R models than by the linear model. Kinetic studies suggest that Co(II) uptake on GO could be described more favorably by the pseudo-second-order kinetic model. A stimulative effect of HA/FA on Co(II) uptake was found at pH 7.0. The results indicated that the uptake is strongly dependent on pH but independent of ionic strength. The uptake of Co(II) on graphene oxide (GO) by an adsorption process as a function of pH and ionic strength in the absence and presence of humic acid (HA) or fulvic acid (FA) was studied using batch technique.
