oxalic acid

 [ok-sal´ik]
a poisonous dicarboxylic acid found in various fruits and vegetables, and formed in the metabolism of ascorbic acid and ethylene glycol. While it is not usually a problem with normal diets, it is seen in high concentrations in certain ornamental plants (such as Diffenbachia), as well as in some bleaches and antirust products. Persons or animals that chew on the plants or otherwise consume the chemical can be poisoned. Oxalic acid is highly toxic and if ingested vomiting should not be induced. If the person is at home, a poison control center and emergency services should be contacted immediately. The acid can be neutralized by administration of calcium by either the oral or the intravenous route. High urinary oxalate concentrations may cause deposition of kidney stones and other urinary calculi.

ox·al·ic ac·id

(ok-sal'ik as'id),
An acid found in many plants and vegetables, particularly in buckwheat (family Polygoniaceae) and Oxalis (family Oxalidaceae); used as a hemostatic in veterinary medicine, but toxic in elevated levels when ingested by humans; also used in the removal of ink and other stains, and as a general reducing agent; salts of oxalic acid are found in renal calculi; accumulates in cases of primary hyperoxaluria.

The Al concentration in oxalic acid increased significantly due to the low Ca concentration in the solution and thereby more oxalate solubility and adsorption on clay minerals and their dissolution.
Moreover, Stepniowski and Bojar [11] developed nanoporous alumina by anodization of 5N+ pure aluminum in 0.3M oxalic acid at still higher temperatures (35, 40, 45, 50AdegC) for different anodizing voltages ranging from 20 to 60 V with an interval of 5 V.
This method, calcination pretreatment combined with ultrasound-assisted by a mixture of oxalic acid and diluted hydrochloric acid leaching, was proven to be an effective way for iron removal from quartz.

The general trend of the aqueous phase in using methanol as the organic phase is as follows: 5 mM oxalic acid > 5 mM ammonium acetate > 0.1% formic acid > 0.1% acetic acid.
Screen bottom board trays were placed in the beehives throughout the treatment period alone and with 3.2 % oxalic acid, 0.5 g thymol, 65 % formic acid in winter (Nov., 2013 - Jan., 2014), spring (Feb., 2014 - April, 2014) and summer (May, 2014- July, 2014) seasons.
In recent decades, efforts have been made to develop new chemically modified electrodes, which can be used directly and rapidly in analytical tests for the determination of important substances, such as pesticides [1], trace metals [2], dopamine [3], ascorbic acid [3] and oxalic acid [4], etc.
Due to the presence of oxalic acid, gallic acid, malic acid, tannins, betulic acid and etc makes it capable as an antibacterial.
