Browning has been controlled by sulfur dioxide (SO2 ) in wine for many years, but other compounds also have the potential to reduce browning. Bentonite, Cufex and SO2 were applied to juice from Riesling grapes Vitis vinifera L. and Vidal grapes, a French-American Hybrid to compare their effects on wine browning. Seven treatments (control, 35 mg/L SO2, 70 mg/L SO2, 120 mg/L bentonite, 240 mg/L b...

Presence of swelling soils under the foundations of civil engineering structures particularly lightly loaded structures has caused serious damages around the globe due to their differential up heaving. In this paper, based on the results of swell tests on bentonite mixed clay, correlations for predicting the swelling parameters (i.e., swell potential and swell pressure) have been proposed. Mixi...

Adsorption and desorption studies on different types of adsorbents, including natural materials such as teak tree bark powder, rice husk, natural bentonite, different algae like Ecklonia maxima, Escherichia coli, Ascophyllum nodasum, Rhizopus nigricans, Cladophora fascicularis, goethite and soils of three nuclear power plant and artificial materials such as Fe oxide-coated sand, goethite pretre...

In order to improve the impermeability of ordinary “cement–water glass” double-liquid grouting material, this study prepares a composite material with sodium bentonite, cement, and water glass as main materials, water-reducing agent, early strength agent activators. study, orthogonal tests were conducted using an L16(45) table test results analyzed regression analysis. Using bentonite instead p...

The description of the geochemical properties of the bentonite backfill that serves as engineered barrier for nuclear repositories is a central issue for performance assessment since these play a large role in determining the fate of contaminants released from the waste. In this study the porewater chemistry of bentonite was assessed with a thermodynamic modelling approach that includes ion exc...

Na-bentonite was prepared and tested as an adsorbent for a dye (Reactive Blue2) removal from aqueous solution. The effect of various experimental parameters was investigated using a batch adsorption technique. In this manner, initial dye concentration, pH of the initial dye solution, temperature and time contact effects upon dye adsorption on Na–bentonite having a structural formula of (Si7.86 ...

Lime sludge is a special type of precipitated calcium carbonate (PCC) recovered from black liquor, which can be used as paper filler in the paper-making process. However, one of the biggest problems when lime sludge is used as filler is that it is difficult to hydrophobically size the filled paper, especially in the case of paper with high filler content. Also, the efficient retention of the si...

BACKGROUND Diaper dermatitis is one of the most common skin disorders of infancy and childhood. The present study aimed to compare the effects of Bentonite and Calendula on the improvement of diaper dermatitis in infants. MATERIALS AND METHODS A double-blind randomized controlled trial, which was conducted on 60 out-patient infants referred to health care centers or pediatric clinics in Khome...
