Hi, I want to recover some nutrient (ammonia and ortho phosphate) from an effluent sludge similar to the wastewater sludge, That contains high total nitrogen value. I used oxygen peroxide and heat to hydrolyze the sludge, I recovered reasonable amount, but at high concentration of peroxide...

thanks to every body. your help is highly appreciated . Thanks ;)

thanks orenda indeed the pensky martens ASTM methode is D 93...the ASTM D92 is the clevland methode. I've contacted the constructor of our automatic apparatus, he mentioned that for the marine fuels with high viscosity, procedure B should be used, but i dont know how to calssify the fuels...

HI for the termination of the flash point " pensky martens " of marine fuels samples ,wich has several viscosity : 30 cST, 60 CST, 80 cST, 180 sCT and 380 sCT0. I use the ASTM D 92. It contain two methodes, A and B. i would like to know which methode should be used A or B ? thanks

It's righ..the calibration of the conductivity within the range of pSM/cm is difficult procedure..i asked the manufacturer, They said that only the manufacturer can calibrate it, otherwise i can use the apparatus' manuel ajust the conductivity cell.

HI need method to make à solution (KCl solution for exemple) to control(calibarate)the JET A1 fuel( kerozene) conductivity's mesurment apparatus "MAIHAK", the conductivity's range is: 0 to 600 picoSiemens/meter, I have not standard solution, so i thaught to do as we do for the water...

Thank's It’s seem a good method to determine the percentage of the contamination by using standard. I will collect sample from each delivery and i'll make my own standard chromatogram library . It’s right that most often the kerosene is contaminated by diesel, in our cases we use a same...

Huy guy In order to determine the contamination of the kerosene’s (JET A1 ) sample with an diesel fuel, I used the gas chromatography, in order to analyze kerosene fuel JET A1, I had injected the non contaminated kerosene in less than 1 microliter of liquid sample into a 50 meter GC...
