Abstraet--Jordanian natural kaolin and bentonite show good catalytic activity towards debutylating 2tert-butylphenol, and varying debutylation vs. isomerization selectivity after acid activation. The resulting catalytic activity of these samples is dependent on the acid employed for activation; the samples treated with acetic acid showed relatively low conversions, whereas those treated with hy...
The adsorptions of reactive procion brilliant red H-EGXL and procion yellow H-EXL by various clay adsorbents were investigated in this research. The research showed that synthetic talc has the highest adsorption capacity for decolorization of both procion type of reactive dyes compared with other clay adsorbents. The removal efficiencies of synthetic talc relatively stable above 80% until the i...
The Critical State Soil Mechanic (CSSM) is a globally recognised framework while the critical states for sand and clay are both well established. Nevertheless, the development of the critical state of sand matrix soils is lacking. This paper discusses the development of critical state lines and corresponding critical state parameters for the investigated material, sand matrix soils using sand-k...
In recent years, several novel cation-independent bioflocculants have been reported, which can avoid the secondary contamination caused by addition of cations. However, compared with cation-dependent bioflocculants, the flocculating mechanism of cation-independent bioflocculants is largely unknown. In this study, a cation-independent bioflocculant MBF-W6 produced by Chryseobacterium daeguense W...
Abstract The paper presents an experimental study on the effect of plastic fines content undrained behavior and liquefaction susceptibility sand-fines mixtures under cyclic loading. results triaxial tests conducted Hostun sand with varying amounts (0–20%) types (kaolin calcigel bentonite) are presented. specimens were prepared different initial densities using moist tamping method, consolidated...
A bioflocculant named MBF-UFH produced by a Bacillus species isolated from sediment samples of Algoa Bay of the Eastern Cape Province of South Africa was characterized. The bacterial identification was through 16S rDNA sequencing; nucleotide sequences were deposited in GenBank as Bacillus sp. AEMREG7 with Accession Number KP659187. The production of the bioflocculant was observed to be closely ...
• Kaolin clay intake is a behavioral marker in rats. Ingestion of lithium chloride solution generates kaolin consumption lactose sucrose does not generate Lactose, we well as chloride, causes nausea Adult rats learn to be shy away from taste paired with the ingestion solution. This study thus aimed elucidate nature this shyness learning. Specifically, by measuring consumption, which good maker ...
Soil structure has been recognised as a key feature in the understanding of soil’s mechanical behaviour, and research efforts have made trying to relate them. However, main difficulties encountered are that numerous factors can simultaneously affect behaviour soils. Among these factors, presence aggregates is decisive for fabric configuration bimodal The aim this paper evaluate effect on soils ...
Abstract This experiment was conducted to determine the effect of kaolin clay application and deficit irrigation on quantitative characteristics pumpkin in a field located Siahbaz village Khoy, Iran. In order investigate yield components ( Cucurbita pepo L.), this experimental considered. An performed with at four levels (complete irrigation, from shoot stage, flowering stage seed filling stage...
