interaction of pb(ii) ion with modified banana shell (mbs) and banana shell (bs) during adsorption fromaqueous solution were investigated. batch experiments were carried out to investigate the effect of contact time,ph, and idmid ion concentration on adsorption efficiency. the favorable pll for maxim= pb(ii) adsorptionwas at 5.0. for the investigated imoi) concentrations (10-80 mph), maximum ad...

Adsorption is a widely used technique for the treatment of wastewater containing dyes, which are pollutants that can have serious impacts on aquatic ecosystems. In this work, activated carbon (AC) was prepared from cashew nut shell (CNS) and to adsorb methylene blue (MB) solution. The CNS AC characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, nitrogen adsorpt...

The present work investigates the potential of Lantana camara, a forest waste, as an adsorbent for the phenol reduction in wastewater. Batch studies were conducted with adsorbent treated with HCl and KOH to determine the influence of various experimental parameters such as pH, contact time, adsorbent dosage, and phenol concentration. The experimental conditions were optimized for the removal of...

Introduction: Arsenic is known as a carcinogenic compound in drinking water. It can cause acute and chronic effects on human health. In this study, the effect of polyamidoamine dendrimer generation 3 (PAMAM G3) as adsorbents for removal of arsenic (V) from aqueous solutions was evaluated. Materials and Methods: Adsorption experiment was studied in batch system and the effect of different varia...

Graphene oxide (GO) is a highly effective adsorbent, and its absorbing capability is further enhanced through its in situ reduction with sodium hydrosulfite as the reductant. Acridine orange is the selected target to eliminate with GO as the adsorbent. Under identical conditions, GO without the in situ reduction showed a maximum adsorption capacity of 1.4 g g(-1), and GO with the in situ reduct...

In this research, the generation process of engineered microsphere agarose adsorbent has been explained that has surfaces with different active sites to adsorb protein nanoparticles into the fluidized-bed system. Also, excellent selectivity of protein nanoparticles, high adsorption capacity, and fast equilibrium rate through the eco-friendly polymeric adsorbents were vital aims in here. Hence, ...

Phosphorous (P) in human urine is among the macronutrients municipal wastewater that has exacerbated eutrophication of water bodies. Adsorption P from using cost effective, environmentally friendly, and efficient adsorbents considered as an attractive method can both mitigate problem augment already strained reserves. In present study adsorption capacity structural properties lateritic soil (LS...

The effective management of sewage sludge materials in an environmentally and economically acceptable way is through the pyrolytic conversion of the sludge to biochar and its use for agricultural purposes. The aims of this work were: (1) to assess the effect of biochar prepared from sewage sludge at two different temperatures (350 ºC and 650 ºC) on the adsorption/desorptio...

background & aims of the study: heavy metals are the most important and main pollutants because of their accumulation and high toxicity even at very low dose and cause serious hazards to ecological system as well as human health. thus, their removal has been challenged from drinking water and industrial waters with different technologies. the purpose of this work is to investigate the removal o...
