Optimization of chromium(VI) biosorption using gooseberry seeds by response surface methodology
The current investigation presents the role of gooseberry (Phyllanthus acidus) seeds as an effective biosorbent for remediating chromium (VI)), a toxic heavy metal pollutant commonly found in effluents from tanneries and relevant industries. Biosorption was affected by pH, temperature and initial metal concentration. Furthermore, there is a need to understand the holistic effect of all...
متن کاملhexavalent chromium removal from aqueous solution using functionalized multi-walled carbon nanotube: optimization of parameters by response surface methodology
background chromium is one of the most commonly used heavy metals in industry. it is known as a pollutant that its discharge into the environment needs special care. objectives the current study aimed to evaluate the functionalized multi-walled carbon nanotubes (f-mwcnts) as a novel adsorbent of chromium in aqueous solutions. materials and methods the virgin mwcnt was protonated using sulfuric ...
متن کاملBiosorption of Hexavalent Chromium from Aqueous Medium with Opuntia Biomass
The biosorption of hexavalent chromium from aqueous solutions by Opuntia cladodes and ectodermis from cactus fruits was investigated. Both types of biomass are considered low-cost, natural, and ecofriendly biosorbents. Batch experiments were carried out to determine Cr(VI) biosorption capacity and the efficiency of the biosorption process under different pH, initial Cr(VI) concentration, and so...
متن کاملOptimization of Biodiesel Production from Castor Oil Using a Microwave Via Response Surface Methodology (RSM)
The purpose of this research work was to investigate the optimum operating conditions for biodiesel production from castor oil using a microwave. The Box–Behnken design of experiment was carried out using the Design Expert 7. A response surface methodology (RSM) was used to analyze the influence of the process variables (molar ratio of methanol to castor oil, catalyst concentration, reaction ti...
