Vinasse was successfully utilized to synthesize carbon–silica composite with a low-cost silica source available in Thailand (sodium silicate, Na2SiO3) and most commonly used source, tetraethyl orthosilicate (TEOS). The composites were prepared by simple one-step sol–gel process varying the vinasse (as carbon source) (Na2SiO3 or TEOS) weight ratio. resulting characterized N2 adsorption, moisture...

Winery wastewater contains high levels of elements such as sodium, phosphorus, potassium, well aschemical oxygen demand, sodium adsorption ratio and pH. This may raise concerns regarding the pollutionof surrounding environment. Environmentally friendly methods recycling, i.e. treatment andre-use, where treated or partially diluted is used for irrigation agricultural crops,are essential. Irrigat...

The purpose of this study was to identify the key factors involved in patulin adsorption by heat-inactivated lactic acid bacteria (LAB) cells. For preventing bacterial contamination, a sterilization process was involved in the adsorption process. The effects of various physical, chemical, and enzymatic pre-treatments, simultaneous treatments, and post-treatments on the patulin adsorption perfor...

Aiming to reduce herbicide leaching, "in situ" adsorption of herbicide-micelle formulations to soils was explored. Sulfentrazone or metolachlor were solubilized in cationic micelles, and these herbicide-micelle formulations were applied to sandy and alluvial soils. Sulfentrazone adsorption to the soils was negligible; however, its adsorption via its solubilization in micelles and their adsorpti...

Nanoscale iron particles decorated graphene sheets synthesized via sodium borohydride reduction of graphene oxide, showed enhanced magnetic property, surface area and Cr(vi) adsorption capacity compared to bare iron nanoparticles.

Attachment assays of a Pseudomonas isolate to fused silica slides showed that treatment with DNaseI significantly inhibited cellular adsorption, which was restored upon DNA treatment. These confirmed the important role extracellular (eDNA) adsorption surface. To investigate eDNA mechanism, single-molecule force spectroscopy (SMFS) used measure silicon surfaces in presence different concentratio...

groundwater is the most widely distributed resource of the earth and groundwater quality evolves rapidly as it passes through the subsurface pathways within the unsaturated zone. increasing urbanization and anthropogenic activities have added to the problem of deficient amount of good quality groundwater. the study area is an industrial hub for textile sector. textile production, particularly d...

With a layered structure, layered double hydroxide (LDH) has potential applications in remediation of anionic contaminants, which has been a hot topic for recent years. In this study, a Cl type Mg-Al hydrotalcite (Cl-LDH) was prepared by a co-precipitation method. The adsorption process of three pharmaceuticals and personal care products (PPCPs) [tetracycline (TC), diclofenac sodium (DF), chlor...

studies by the us salinity laboratory, using gapon rule, led to the value of 0.01475 (mmol l-1)-0.5for the modified gapon selectivity coefficient (k'g). nevertheless, the results of subsequent research reveled that k'g isn’t constant and could take on a wide range of values depending on soil properties. the aim of this study was to determine the relationship between exchangeable sodiu...

Anion adsorption on the aluminum oxide, gibbsite, was investigated as a function of solution pH (3Y11) and equilibrium solution Mo (3.13, 31.3, or 313 Kmol/L), P (96.9 Kmol/L), or S (156 Kmol/L) concentration. Adsorption of all three anions decreased with increasing pH. Electrophoretic mobility measurements indicated a downward shift in point of zero charge, indicative of an inner-sphere adsorp...
