The extensive consumption of aluminum, combined with the shortage existing raw materials, and particularly bauxite, necessitates exploitation alternative materials for production alumina. present paper focuses on possible use kaolin, as an abundant, cheap high-aluminum content material, in alumina production, via application Aranda-Mastin technology leaching step. From this point view, experime...

Concerns are being raised that microplastic pollution can have detrimental effects on the feeding of aquatic invertebrates, including zooplankton. Both small plastic fragments (microplastics, MPs) produced by degradation of larger plastic waste (secondary MPs; SMPs) and microscopic plastic spheres used in cosmetic products and industry (primary MPs; PMPs) are ubiquitously present in the environ...

Kaolin yüzeyine perovskit yapılı BiFeO3 (BFO) nanoparçacıklarının yerleştirilmesiyle Kaolin-BiFeO3 (KBFO) nanokompoziti hazırlandı. Saf kaolin (K), saf BFO ve hazırlanan KBFO nanokompozitin fotokatalitik aktiviteleri UVA görünür bölge ışımaları altında katyonik bir boyar madde olan kristal viyole (KV)’nin bozunması incelenerek değerlendirildi. nanokompozitinin diğer katalizörlere nispeten daha ...

OBJECTIVE To determine reference values for kaolin-activated thromboelastography in echocardiographically normal cats. ANIMALS 30 healthy cats without evidence of cardiomyopathy on echocardiographic examination. PROCEDURES All cats underwent echocardiographic examination, the findings of which were reviewed by a board-certified cardiologist. Cats that struggled (n = 10) received mild sedati...

-The reaction of kaolin with NaC1 was followed by dynamic thermal analysis and mass spectrometry under/'42, CO2, and air atmospheres and in a 10-5-torr vacuum. The weight loss was a function of the atmosphere used and, according to mass spectrometry, was due to the evolution of H20, HC1, and very small amounts of H2. HC1 was formed only after the release of 85% of the hydroxyl content of the ka...

Gala' apples trees were treated with kaolin (Surround) in mid-July, and fruit were sampled 1 and 7 days after treatment. Apples were gently rinsed with cold deionized water to remove loose surface material. Small sections of cuticle tissue were shaved from the fruit surface with a razor blade and flash frozen on an aluminum block held at -190oC with liquid N2. The tissue was freeze-dried, coate...

In 1961, 553 Cornish china clay workers had been exposed to kaolin dust for periods exceeding five years, and evidence of kaolinosis was seen in 48 (9 %). No kaolinosis was found in men who had been exposed for less than five years. Workers in the more heavily exposed jobs of milling, bagging, and loading showed a prevalence rising from 6% in those with between five and 15 years' exposure to 23...
