The occurrence of microcystins (MC) during aquatic blooms of cyanobacteria in eutrophicated freshwater body has increasingly become an environmental and health concern worldwide. An experimental study was conducted to investigate the adsorption of two common variants of microcystins, MCLR and MCLW, onto SPM at different pH values. The results showed that most microcystins spiked into an SPM sol...

In adsorption study, to describe sorption process and evaluation of best-fitting isotherm model is a key analysis to investigate the theoretical hypothesis. Hence, numerous statistically analysis have been extensively used to estimate validity of the experimental equilibrium adsorption values with the predicted equilibrium values. Several statistical error analysis were carried out. In the pres...

conclusions the findings of this study showed that the modification of natural zeolites can achieve higher adsorption capacity for organics. in addition, based on the results, natural zeolite being modified with sds as a cationic surfactant had good efficiency for the adsorption of nom. results the results indicated that sds-modified zeolite showed greatly enhanced adsorption capacity. findings...

Removal of brilliant red (C. I. Reactive Red 2) from aqueous solutions by adsorption on fish scales of Labeo rohita was investigated. Batch adsorption experiments were carried out under different experimental conditions such as contact time, initial concentration of dye solutions, temperature and pH of the solution. The optimum pH for the adsorption experiment was found to be 7.2. The equilibri...

Theoretical isotherms for monolayer adsorption on heterogeneous surfaces have been obtained on the basis of the Langmuirian local isotherm and three different distribution functions of adsorption energies (Boltzmann, quasi-Gaussian and shifted quasi-Gaussian distribution functions). The isotherm obtained with the Boltzmann distribution function proposed 40 years ago by Glueckauf predicts well t...

Covalent grafting of poly(ethylene glycol) (PEG) to pharmaceutical proteins, "PEGylation", is becoming more commonplace due to improved therapeutic efficacy. As these conjugates encounter interfaces in manufacture, purification, and end use and adsorption to these interfaces may alter achievable production yields and in vivo efficacies, it is important to understand how PEGylation affects prote...

Biochar converted from agricultural residues or other carbon-rich wastes may provide new methods and materials for environmental management, particularly with respect to carbon sequestration and contaminant remediation. In this study, laboratory experiments were conducted to investigate the removal of phosphate from aqueous solution by biochar derived from anaerobically digested sugar beet tail...
