Adsorption of Copper by using Microwave Incinerated Rice Husk Ash (MIRHA)
Many non-conventional adsorbent have been studied as economic alternative to commercial activated carbon and mostly agricultural waste have been introduced such as rubber leaf powder and hazelnut shell. Microwave Incinerated Rice Husk Ash (MIRHA), produced from the rice husk is one of the low-cost materials that were used as adsorbent of heavy metal. The aim of this research was to study the fe...
متن کاملAdsorption of Copper from Aqueous Solution Using Low- Cost Adsorbent
In this study activated carbon prepared from Adathoda vasica stem was used as adsorbent to remove Cu from an industrial waste water. For this purpose, high grade CuSO4.5H2O was used as heavy metal sample. Laboratory experimental investigation was carried out to identify the effect of pH (1.50 – 5.5), agitation time (30-240 min) varying temperature (30-50 ̊C) and varying biomass quantities (2,4,6...
متن کاملCharacterization of H3PO4-Treated Rice Husk Adsorbent and Adsorption of Copper(II) from Aqueous Solution
Rice husk, a surplus agricultural byproduct, was applied to the sorption of copper from aqueous solutions. Chemical modifications by treating rice husk with H3PO4 increased the sorption ability of rice husk for Cu(II). This work investigated the sorption characteristics for Cu(II) and examined the optimum conditions of the sorption processes. The elemental compositions of native rice husk and H...
متن کاملAgricultural waste material as potential adsorbent for sequestering heavy metal ions from aqueous solutions - a review.
Heavy metal remediation of aqueous streams is of special concern due to recalcitrant and persistency of heavy metals in environment. Conventional treatment technologies for the removal of these toxic heavy metals are not economical and further generate huge quantity of toxic chemical sludge. Biosorption is emerging as a potential alternative to the existing conventional technologies for the rem...
متن کاملAdsorption of Ni(II) and Cd(II) from Aqueous Solutions Using Modified Rice Husk
Background and purpose: Recently, release of pollutants such as heavy metal ions to the environment becomes one of the most important problems for soil and water. The present study was conducted to introduce modified rice husk (RH) as a new low-cost adsorbent. Materials and Methods: In this study, tartaric acid modified RH (TARH), was used as an adsorbent for removal of Ni(II) and Cd(II) from w...
