Resumo: Knowledge of a rock's composition allows for inferences regarding several properties, ranging from its physical characteristics to its solubility. This study aimed to evaluate the use of different extractants to solubilize the K present in rocks as a potential source of nutrients and the effects of extractant contact time and temperature on rock solubilization. Samples of two rocks and a mineral concentrated from a granitic rock were treated with ammonium dihydrogen phosphate (NH4(H2PO4)), calcium dihydrogen phosphate (Ca(H2PO4)2), sodium hydroxide (NaOH) and water (control). Sample-extractant treatments were performed using a water bath shaker at temperatures of 25 and 50°C for periods of 3, 7, 10, 20, and 30 days. The amounts of K extracted from rocks using the extractants were in the following order: NH4H2PO4>Ca(HPO4)2>NaOH>water. The sequence of K release (ppm) based on the rocks studied was as follows: nepheline syenite>green banded argillite>concentrated biotite. Increasing the extractant contact time and temperature enhanced the solubilized K content.

O objetivo do presente estudo foi avaliar o uso de diferentes extratores na solubilização do potássio (K) presente em rochas potenciais fontes de nutrientes e os efeitos do tempo de contato dos extratores e temperatura na solubilização das rochas. Amostras de rochas e mineral concentrado de rocha granítica foram tratadas com di-hidrogenofosfato de amônio (NH4(H2PO4)), di-hidrogenofosfato de cálcio (Ca(H2PO4)2), hidróxido de sódio (NaOH) e água (controle). Os tratamentos rochas-extratores foram submetidos ao banho de agitação em água a temperaturas de 25 e 50°C durante períodos de 3, 7, 10, 20, e 30 dias. As quantidades de K extraídos de rochas usando os extratores foram na seguinte ordem: NH4H2PO4> Ca(H2PO4)2> NaOH> água. A sequência de solubilização de potássio (ppm) baseado nas rochas estudadas foi a seguinte: nefelina sienito> argilito verde bandado>concentrado de biotita. O tempo de contato dos extratores e temperatura aumentaram o conteúdo de K solubilizado.Editora da Universidade Estadual de Maringá - EDUEM2018-08-17T17:27:07Z2018-08-17T17:27:07Z2016info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfREIS, D.
