Oxalis corriculaza L. O. corymbosa DC Sha Jiang Cao (Wood sorrel) (leaf) Oxalate, vitamin C, calcium, citric acid, malic acid, tartaric acid.50 Antidote to arsenic and mercury, for bruises, clots, diarrhea, fever, influenza, snakebite, urinary infections. [Pg.119]

Arsenic in soilds has been fractionated by Jackson s T28) procedure for soil phosphorus (15. 27). In this laboratory, a modification of Jackson s procedure is being used on sediment solids. A series of 1 molar solutions of NH4CI, NH4OH, acid ammonium oxalate (29) and HCl are used in sequence. The chloride fraction, or exchangeable fraction, contains weakly adsorbed, coulombically bound arsenic. The hydroxide fraction, contains iron and aluminum arsenate precipitates and surface precipitates (i.e. adsorbed arsenic species having both chemical and coulombic bonding to oxide surfaces). The oxalate, or reductant soluble fraction, contains arsenic occluded in amorphous weathering products. The acid, or calcium, fraction contains arseno-apatites. [Pg.714]

By far the most serious interference effects in the determination of calcium are due to anions such as phosphate, sulphate, arsenate and oxalate, and to elements such as aluminium, beryllium, boron, chromium, iron and molybdenum which can exist as anions in the flame. These all give rise to reductions in line intensities, probably due to the formation of compounds which are either of low volatility or are not dissociated. [Pg.147]
