Abstract The nickel cobalt aluminium oxides (NCA) type Li-ion battery is a type of battery currently used in electric vehicles. The UGM battery team has recycled this type of battery to obtain high purity lithium metal. Aside from lithium, the NCA battery contains high-value metals, nickel is one of them. This experiment aims to test the ease of nickel to chelate with disodium ethylene diamine tetraacetate (EDTA). The experiment was carried out by means of a triple neck flask for 4 hours. The samples were taken at certain minutes and then fitted using a pseudo homogeneous first-order reaction equation. The chelate formed was further processed through multilevel precipitation or electrodialysis to separate nickel. Based on the experiment, nickel formed chelates optimally at 60°C using 0.086 M EDTA with the reaction constant for nickel being 1.4819 min−1. The Arrhenius constant and activation energy for nickel were 3.48×1011min−1 and 76,907 J/mole, respectively.

A survey was made of the extractive power of 15 reagents for organic matter from the A0 and B21 horizons of a podzol. All were inorganic except disodium ethylene diamine tetraacetate (EDTA-Na2) and their solutions ranged in pH from 1.4 to 13.1. The amount of organic matter extracted varied with horizon and with extractant. While only NaOH removed appreciable amounts from the A0 horizon, Na4P2O7, Na3PO4, NaF, Na2CO3, NaOH, HF and EDTA-Na2 extracted > 80 per cent of the organic matter of the B21 horizon. No organic matter from the A0 horizon extracts passed through a cellulose membrane on dialysis against distilled water whereas the B21 extracts lost from 20 to 70 per cent of their carbon content. The ash content of the non-dialyzable portion of the B21 horizon extracts was high (20–40 per cent), indicating the possible presence of complexes of organic matter with metals such as Fe and Al and with clays. The carbon contents of the same materials ranged between 40 and 50 per cent, suggesting that all extractants removed essentially a similar type of material.
