Occupational exposure to nickel salts in electrolytic plating.
An occupational hygiene survey was made in 38 nickel plating shops in Finland and exposure to nickel was studied by means of biological measurements and, in three shops, by using air measurements. The average after-shift urinary nickel concentration of 163 workers was 0.16 mumol l.-1 (range 0.001-4.99 mumol l.-1). After the 1-5 week vacation the urinary nickel concentration was higher than the ...
متن کاملElectrolytic Chlorogen
appeared a report on Electrolytic Chlorogen by Captain W. Hodgkinson, r.e., and Mr. C. M. Hutchinson, c.i.ii., Imperial Agricultural Bacteriologist of the Agricultural Research Institute, Pusa. The principal objects of this enquiry, which were carried out under the auspices of the Army Department (Simla), were to determine the possibility of preparing in India from indigenous materials and by s...
متن کاملElectrolytic Chlorogen
Sik.?I have received the enclosed letter from Mr. Hutchinson of Pusa in regard to the remarks on Electrolytic Chlorogen contained in the report of my paper on "The Selection of a Disinfectant" in the May issue of the Gazette. Whilst I am not entirely in agreement with Mr. Hutchinson in his estimation of costs based only 011 a phenol coefficient,? (Lysol, for instance, is extensively used by gyn...
متن کاملELECTROLYTIC RECOVERY OF COPPER FROM CHELATED WASTE STREhMS
Electroless plating is a chemical reduction process which depends upon the catalytic reduction of a metallic ion in an aqueous solution containing a reducing agent without the use of electricity (1). Cahill (2) showed that the cupric ion could be reduced autocatalytically with formaldehyde in an alkaline solution. Okinaka (3 ) established that the overall reaction of the catalytic copper platin...
متن کاملNitrate removal from groundwater using electrolytic reduction method
Nitrate (NO3) contamination of groundwater is a major concern throughout intensive agricultural areas. In the present laboratory scale study, an electrolytic reduction method employing copper cathode and insoluble triple mixed oxide anode was studied for the denitrification of groundwater in a divided cell. Influence of process parameters such as pH, current density and time were studied and th...
