Titanium dioxide purity can be determined using various analytical methods. The most popular being X-ray fluorescence spectroscopy (XRF), which can quantify the amount of titanium and other elements present. Another method is X-ray powder diffraction (XRPD), which measures the purity of crystalline materials. Other techniques include Raman spectroscopy and inductively coupled plasma mass spectrometry (ICP-MS). To get the most accurate results, a sample of the titanium dioxide should be prepared and examined under controlled laboratory conditions by trained professionals.

The metal was rediscovered four years later in the Austrian Alps by German scientist Martin Heinrich Klaproth. Titanium was named after the ancient Greek god Titan after he identified it as a new element.

Yes, sulfur dioxide is considered a greenhouse gas. It can contribute to global warming and climate change by trapping heat in the Earth’s atmosphere. However, it’s worth noting that sulfur dioxide also contributes indirectly to cooling the Earth by forming aerosols in the atmosphere that reflect sunlight back into space.
