TL;DR: Immediate treatment should include urgent induction of emesis, administration of ascorbic acid as an antidote, followed by supportive treatment.
Abstract: Sodium dichromate ingestion in children is uncommon and potentially lethal. The most appropriate management is uncertain because of the lack of sound data contained in the few reports of successfully treated patients. Immediate treatment should include urgent induction of emesis, administration of ascorbic acid as an antidote, followed by supportive treatment.

TL;DR: In this article, the authors proposed a coal gangue catalytic combustion additive, which comprises the following components of waste residue from potassium dichromate production, waste residues from sodium dichromates production, sodium aluminosilicate, ferrocene, ferric oxide, magnesium silicate, potassium permanganate, sodium dodeeyi benzene sulfonate, ammonium bicarbonate, industrial sodium chloride, rare earth elements, sodium carbonate, and plant debris.
Abstract: The invention provides a coal gangue catalytic combustion additive. The additive comprises the following components of waste residue from potassium dichromate production, waste residue from sodium dichromate production, sodium aluminosilicate, ferrocene, ferric oxide, magnesium silicate, potassium permanganate, sodium dodeeyi benzene sulfonate, ammonium bicarbonate, industrial sodium chloride, rare earth elements, sodium carbonate, sodium nitrate and plant debris. The invention has the characteristics of catalytical combustion-supporting, sulfur fixing and coal gangue net calorific value combustion improving, enables the coal gangue to be sufficiently burnt and reduces the emissions of the harmful gas.

TL;DR: In this article, a method for recovering sodium acid chromate from chrome-containing electroplating sludge was proposed, which can exceed 90 % in terms of recovery of chrome from electroplated sludge.
Abstract: The invention discloses a method for recovering sodium acid chromate from chrome-containing electroplating sludge. The electroplating sludge is blended with Na2CO3 according to a certain proportion and is baked at a certain temperature to obtain Na2CrO4, Cr is oxidized into Cr chrome and aluminum and zinc are taken as corresponding oxides; Cr, Al and Zn are dissolved in liquid by water soaking to generate respective salt, and the solid containing the metals such as Ni, Cu, Fe, Ca, Mg, and the like, is filtered and separated; the Na2CrO4 solution is transformed by hydrolysis acidification and Al2(OH)3 and Zn(OH)2 are removed to realize the separation of Zn, Al and Cr; the chrome-containing solution is acidated into sodium acid chromate (Na2Cr2O7), cooled after being concentrated to a certain volume, and filtered to remove sodium sulfate; the sodium acid chromate solution is processed by condensation, crystallization, centrifugation and drying to obtain sodium acid chromate finished product. By adopting sodium treatment and oxidation process, the rate of recovering chrome from chrome-containing electroplating sludge can exceed 90 %, and the resource utilization of electroplating sludge can be realized.
