Abstract The tofu industry is currently growing very rapidly both on a home scale and factory scale, in the process of making solid liquid waste are produced. Solid usually used for animal feed, while not treated. Tofu industrial contains high Total Suspended (TSS), if disposed directly into water it can pollute aquatic ecosystem. One way to reduce pollution use activated charcoal from plantain...

The adsorption of Co(II) from the simulated solution was investigated using zeolite NaX derived rice husk ash as an alternative adsorbent. behavior depended strongly on equilibrium pH, Co (II) concentration, dosage, and reaction time. high efficiency by obtained under conditions: pH 3.0, 100 mg/L Co(II), 5 g/L NaX, a time 75 min. loading onto well-fitted to Freundlich isotherm capacity around 3...

The present investigation was carried out about the corrosion inhibition and adsorption behavior of Neem and Hibiscus, as a green inhibitor of Zinc corrosion in acidic mediated of corrosion causing soil microbes by using weight loss and thermodynamic studies. Even analyze the quantitatively and qualitatively biochemical substances present in Neem and Hibiscus leaves of aqueous and ethanol extra...

The biosorption of lead(II), cadmium(II) and nickel(II) ions from aqueous solution by Spirulina platensis was studied as a function of time, concentration, temperature, repetitive reactivity, and ionic competition. The kinetic results obeyed well the pseudo second-order model. Freundlich, Dubinin Radushkevich and Temkin isotherm models were applied in describing the equilibrium partition of the...

adsorption of 1-butanol, phenol, and p-nitrophenol on activated carbon havebeen studied. the results were used to testifying the validity of different modelsbased on thermodynamic principles: freundlich, langmuir and henry isotherms.the maximum capacity of adsorbent for three compounds was determined, theconstants of equilibrium were determined by freundlich isotherm and virialisotherm expressi...

Samples of the composite cellulose with polyaniline (Cel/PAn), in which PAn is doped hydrochloric acid synthesis process, were synthesized under mass ratio Cel : aniline (An) equal 2 1. The was carried out by oxidation ammonium peroxydisulfate (APS) aqueous 0.5 M solutions presence a suspension bleached cellulose. adsorption capacity produced samples Cel/PAn regarding Cr(VI) studied used electr...

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.     methods: adsorption experiment was studied in batch system and the effect of different variables like p...

in this research, chitosan was used for the removal of cr (vi) ions from aqueous solution. the effect of parameters like solution ph, initial cr (vi) concentration, agitation time, amount of adsorbent and agitation speed on the adsorption process was studied. the experimental equilibrium data were analyzed by using various models such as langmuir and freundlich. freundlich isotherm model fitted...
