چکیده
This study deals with the issue of copper separation from acidic etching solutions formed during process production printed circuit boards (PCBs) for electrical and electronic industries. The article describes selected methods summarizes results an experiment, in which efficiency recovery depleted acid by cementation precipitation method was verified. In cementation, iron form metallic swarf used as a precipitant. To verify method, CaCO3 limestone, Ca(OH)2 calcium hydroxide NaOH solution were used. During measurement, amount Cu observed both dependence on time, temperature, pH.Keywords: Acid etching; Cementation; Copper; Precipitation; Printed (PCB).

Direct Recycling of Copper from Etching to Plating
In the manufacture of printed circuit boards, the copper dissolved during etching can be used to replace the copper needed for plating using a liquid ion-exchange agent. Extraction and stripping studies demonstrated the feasibility. The quality of the etchant was not affected by the presence of the ion-exchange agent. Good-quality deposits were plated from the stripping solution with a current ...
متن کاملEnantiomer separation of acidic compounds
CHIRALPAK QN-AX and QD-AX are anion exchanger chiral stationary phases providing specifi c enantioselectivity for acidic compounds. In this Application Note, we demonstrate that the application of these columns can be extended to supercritical fl uid chromatography (SFC) for enantiomer separation of acidic compounds. Using the advantages of the advanced technology of the Agilent 1260 Infi nity ...

Background: Industrial development has caused the release of various pollutants including heavy metals into the environment. These toxic compounds are extremely dangerous to living beings and the environment due to their non-biodegradability, severe toxicity, carcinogenicity, the ability to be accumulated in nature and the ability to contaminate groundwater and surface water. The aim of the pre...
متن کاملHydrochemically separation of gold from Copper Anode Slime by means of Thiourea solution
However, the conventional gold recovery process is cyanidation, due to the recent environmental laws; researchers are looking for alternative methods for the recovery of gold. Furthermore, the copper anode slime is one of the most important secondary sources of gold (about 1200 ppm). So, the main objective of the current work is gold separation from copper anode slime as a rich secondary source...
متن کاملPreparation of Nanochitosan as an Effective Sorbent for the Removal of Copper Ions from Aqueous Solutions
The most important pollutants in wastewater are heavy metal ions. In this paper, the effects of various parameters such as pH, contact time, initial concentration, and temperature on the adsorption of Cu (II) by nanochitosan (NCS) was investigated in batch experiment. Nanochitosan was prepared based on ionic gelation and characterized by means of Fourier Transform Infrared Spectroscopy (FTIR),...
