Table 2: H2SO4
mediated Bromination of Methylketones
At 0.1 M H2SO4
concentration, peak size of franklinite and magnetite was increased, this is due to the fact that ZnFe2O4 is slightly soluble in dilute solution of sulphuric acid however, at high concentration (1 M), reduction in peak is responsible for the reaction of same phase in sulphuric acid solution.
Therefore, 5 mL of 2 M H2SO4
can recover the As(V) ions from the banana peel surface.
3 illustrates the FAME profile of different lipid configuration presence in palm oil sludge with the effect of different methanol to sample ratio at fixed reaction conditions: 70 [degrees]C, 12v/v% H2SO4
and 120 minutes.
The method requires up-front costs due to specialized equipment, but ESS has the equipment and experience needed to conduct this test method for facilities that are currently or potentially regulated for H2SO4
. ESS has requested and received variances from state regulators for use on biomass boilers, paper mills, and ceramic kilns for compliance-level testing.

And she knew H2SO4
was sulphuric acid, which impresses me.
TIP 0606-26 Sulfuric acid (H2SO4
) safe storage and handling
Specifically, the new process reduces chemical consumption by greater than 95 percent, with the complete elimination of H2SO4
and reduction of H2O2.
This technology has allowed ST to convert from its use of conventional piranha-based chemistry to the more benign DIO3 chemistry in almost all FEOL resist stripping and post-ash residue removal steps, nearly eliminating the use of sulfuric acid (H2SO4
) and significantly reducing the use of hydrogen peroxide (H2O2).
Examples of more familiar acids are hydrochloric acid (HCI), sulfuric acid (H2SO4
), and vinegar, which is acetic acid (CH3COOH).
But it can catalyze sulfur dioxide (SO2)--also prevalent in industrial exhaust--to sulfuric acid (H2SO4
), which is a potent respiratory irritant.
In fifth operation, ANF Rawalpindi intercepted a pickup near Jandu Garran, Sangjani, Taxila, District Rawalpindi and recovered 140x Cans of Sulphuric Acid (H2SO4
) weighing 6300 liter from the vehicle.
Finally, the samples were soaked with (0.5 M, 1.0 M or 1.5 M) (NH4)2SO4 (H2SO4
) solution (15 mL*g-1 catalyst) for 24 h, filtered, dried and calcined at 500 AoC for 3 h.
