Laboratory and full-scale experiments were conducted for enhancing the coagulation of stabilised surface waters with high organic content by permanganate preoxidation. It was indicated that permanganate preoxidation enhanced both the processes of coagulation and filtration of selected surface waters, River Songhua water, Qitaihe Reservoir water and Ba Reservoir water. Permanganate preoxidation ...

In situ chemical oxidation (ISCO) is one of the effective technologies used for source zone remediation of dense nonaqueous phase liquids (DNAPLs) such as chlorinated solvents in the subsurface environments. In karst systems, DNAPL source zones reside in epikarst where the contaminant is generally trapped in the soil or at the carbonate bedrock contact. The efficiency of oxidation of residual t...

Many chemicals used as medical treatments can cause chemical burns as an untoward side effect. One of such chemicals is potassium permanganate. It is a caustic chemical used as a disinfectant. The most common sites of burn by potassium permanganate are exposed sites like the face and hands. Chemical burns in the perianal and anal region are rare in clinical practice and even sparser in the pedi...

Severe potassium permanganate poisoning (more than 10 g of potassium permanganate) is invariably associated with massive systemic upset and death. Multiple organ damage has been recognized as an inevitable consequence of such an overdose, although pancreatitis has not been previously reported. Death due to cardiovascular collapse and profound hypotension is a common end point in those who reach...

The permanganate method was applied to tissues from 35 cases of amyloidosis seen at the University Hospital. Kuala Lumpur. This method is based on the difference in affinity of various chemical types of amyloid for Congo red dye after treatment with potassium permanganate. Our findings agree with the concept that amyloid of largely immunoglobulin light chain composition (primary and myeloma amy...

BACKGROUND Potassium permanganate is used clinically as an antiseptic and antifungal agent. Ingestion of potassium permanganate may result in damage to the upper gastrointestinal tract. Burns and ulceration of the mouth, esophagus and stomach occur due to its action. Emergency endoscopy is useful to assess the severity of damage and also to guide management. METHODS We reported a patient pres...

In order to improve adsorption capacity of granular activated carbon (GAC), potassium permanganate was used to react with GAC to change the surface properties and improve the adsorption capacity of GAC. By batch experiments, improvement of adsorption capacity of potassium permanganate modified GAC (GACM) was studied. The influence of adsorption time, temperature, ratio of phenol with GAC/GACM, ...

Whilst chemical cleavage of mismatch (CCM) detects all point mutations in DNA, its widespread use has been hampered by the complex multistage methodology and the need for toxic chemicals, in particular osmium tetroxide. Here we show that osmium tetroxide can be replaced by potassium permanganate, giving the same spectrum of mutation detection, but with greater sensitivity. The use of potassium ...

Rapid, simple and sensitive validated spectrophotometric methods have been described for the assay of pipazethate HCl (PiCl) and dextromethorphan HBr (DEX) either in pure form or in pharmaceutical formulations. The proposed methods were based on the oxidation of the studied drugs by a known excess of potassium permanganate in acidic medium and estimating the unreacted permanganate with amaranth...
