In this paper, the effect of periodate (IO4−) on the ultrasonic degradation at 300 kHz of Brilliant Blue R (BBR), an organic dye pollutant, was investigated. The experiments were realized in the absence and presence of periodate for various operating conditions including initial solution pH (2–...

Peanut proteins conarachin II, conarachin I and arachin were found to behave as highly selective fluorescence sensors for periodate amongst a set of different anions. The interactions of the proteins with periodate were also confirmed by other spectral methods and enzyme linked immunosorbent ass...

Sterilization of biomaterials by gamma irradiation should not change its structure, since this may affect also its bioactivity. In this work, dextrin and periodate-oxidized dextrin (ODEX), both irradiated and non-irradiated, were hydrolysed by α-amylase and the obtained oligosaccharides were fr...

Manganese and ammonium pollution in surface water sources has become a serious issue. In this study, a pilot-scale filtration system was used to investigate the effect of ammonium on manganese removal during the simultaneous removal of ammonium and manganese from surface water using a manganese ...

Beta-N-methylamino-L-alanine (BMAA), a new cyanobacterial neurotoxin produced by more than 20 genera of cyanobacteria, has been associated with amyotrophic lateral sclerosis/parkinsonism–dementia complex (ALS/PDC) or Alzheimer's disease. Although BMAA has been shown to be removed in drinki...

Previous studies have shown that ammonium and manganese could be removed from water by biofilm in a trickling filter. However, it always takes several months to start up a biofilm filter. In this study, by oxidizing manganese and ferrous ion from raw water using potassium permanganate continuous...

Alkaline potassium permanganate solution (APP) was applied to the pretreatment of corncob with a simple and effective optimization of APP concentration, reaction time, temperature and solid to liquid ratio (SLR). The optimized pretreatment conditions were at 2% (w/v) potassium permanganate with ...

The sorption equilibria and kinetics of zinc from aqueous solution on both untreated and permanganate treated pine chips were investigated. The sorption kinetics were best described by pseudo-second-order equation and the sorption isotherms were well fitted by a Langmuir model for both untreated...

This paper evaluates the oxidation of an antibacterial agent, chlorophene (4-chloro-2-(phenylmethyl)phenol, CP), by permanganate (Mn(VII)) in water. Second-order rate constant (k) for the reaction between Mn(VII) and CP was measured as (2.05 ± 0.05) × 101 M−1 s−1 at pH 7.0 for an initial CP co...

The Dutch drinking water sector is actively investigating methods to reduce arsenic (As) to

In this study, the double-edge role of permanganate in sulfamethoxazole (SMX) photodegradation with a recyclable catalyst was revealed for the first time. The role of the catalyst under different UV wavelength, the role of permanganate in the treatment process, the effects of permanganate dosage...

Self-oxidation/dissociation of some quaternary ammonium permanganates (QAPs), such as cetyltrimethylammonium permanganate (CTAP) and tetrabutylammonium permanganate (TBAP), have been studied spectrophotometrically in six different organic solvent media of different polarities wherein the compoun...

The thermal decomposition of ammonium permanganate was studied by thermogravimetry-mass spectrometry (TG-MS). A Perkin Elmer TGS-2 thermobalance and a Hiden’s HAL 3F/PIC mass spectrometer equipped with a fast ion counter was used.Products of thermal decomposition of ammonium permanganate are ox...

The non-polar internal cavity of β-cyclodextrin (β-CD) has been exploited for the entrapment of the hydrophobic tails of two water insoluble quaternary ammonium permanganates (QAPs): cetyltrimethylammonium permanganate (CTAP) and tetrabutylammonium permanganate (TBAP), for solubilization in aq...

The kinetics and mechanism of the thermal decomposition of ammonium iodate have been studied by measuring the loss in weight and the pressures of the gases evolved. Ammonium iodate decomposes at a measurable rate between 145–165° and explodes above 180°. The presence of ammonia, however, grea...

A novel attapulgite/polyaniline/phosphomolybdic acid-based amperometric sensing platform was constructed for the determination of iodate. Nanostructured attapulgite was utilized for reducing agglomeration of polyaniline particles, and the as prepared attapulgite/polyaniline composite was used to...

:The presence of ammonium (NH4+) in drinking water treatment results in inhibition of disinfection efficiency and formation of nitrogenous disinfection by-products. Our previous study found monochloramine (NH2Cl) photolysis under 254 nm UV irradiation can be effective for removal of NH4+; howeve...

Lead (II) is the hazardous and toxic material for human being and animals since it damages the central nervous system causing disorder of the circulatory system and brain. Hence to overcome the toxic effects of lead, rapid, simple and effective methods to detect Pb (II) is necessary. Pb (II) ISE...

A nanocomposite was fabricated comprising nanoparticles of carbon and poly(ortho-aminophenol) by electropolymerization technique.
