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 variable...

We investigated the bioremoval of Cd(II) in batch mode, using dead and living biomass of Trichoderma viride. Kinetic studies revealed three distinct stages of the biosorption process. The pseudo-second order model and the Langmuir model described well the kinetics and equilibrium of the biosorption process, with a determination coefficient, R(2)>0.99. The value of the mean free energy of adsorp...

The main objective of the present study is to effectively utilize the de-oiled algal biomass (DAB) to minimize the waste streams from algal biofuel by using it as an adsorbent. Methylene blue (MB) was used as a sorbate for evaluating the potential of DAB as a biosorbent. The DAB was characterized by SEM, FTIR, pHPZC, particle size, pore volume and pore diameter to understand the biosorption mec...

in the present investigation the biosorption potential of rosa gruss an teplitz (red rose) waste biomass (rrwb) for the removal of pb(ii) and co(ii) from aqueous solutions was studied. the effect of different process parameters such as ph, biosorbent dose, biosorbent size, temperature, contact time, initial metal concentration and pretreatments on the biosorption capacity of this waste biomass ...

This work aims to characterize biosorbent materials based on seaweed present on the littoral of Baixada Santista (São Paulo state, Brazil), and test their adsorption properties to remove heavy metal cations (Co+2, Pb+2, and Cd+2) in water, aiming its future application situ remediations degraded ecosystems. Three types of nat...
