I use Sephadex SP-C25 and Dowex 50×2 cation exchange resins to clean up
reaction mixtures during syntheses of Co(III) complexes – trouble is, there
always seems to be something that binds irreversibly to the column and I end
up with a load of dirty resin that even 0.2M HCl (sephadex) or 6M HCl (
dowex) won’t shift. Does anyone in netland have any hints on how to clean
these resins up? Has anyone tried elution with mild reducing agents? The
resins are so expensive they can’t just be chucked. Any tips would be
appreciated.

Thanks…

Allan

Hi there
I am going to buy the Chemwindow for my PC, could someone tell me
where is the address of Soft Shell Inc, so I can have a mail order
thanks in advance:-)

 What I especially want to emphasize are any superlatives of the
elements, i.e. , the chemical properties and the nuclear properties,
each element has which are unique, aside from the fact of the
uniqueness of atomic number. Please point out any superlatives which I
have overlooked. There are mistakes in these descriptions please notify
me of the mistakes.

Element 27, cobalt, Co, is a lusterous, silvery-blue, hard metal,
ferromagnetic.  Cobalt blue is a color pigment to tiles, porcelains,
and enamels. Al-Ni-Co alloys are of exceptional magnetic strength.
High temperature alloys containing cobalt make jet propulsion engines.
Cobalt is biologically an essential trace element for both plants and
animals.  Cobalt is a constituent of vitamin B12.

Element 28, nickel, Ni, is a silvery white metal, lusterous, malleable,
and ductile, hard and durable, ferromagnetic. Ni is uniquely resistant
to the action of alkalies. Nickel is used extensively for making
stainless steel. Nickel is present in all biological systems.

Element 29, copper, Cu, is a reddish metal, malleable and extremely
ductile, with high thermal and electrical conductivity.  Copper’s high
electrical conductivity is its most important property and important
use. Only silver has a greater volumetric conductivity than copper, and
on a relative basis in which silver is rated at 100 then copper is 94,
aluminum 57, and iron at 16. Mixed valence copper oxides are
superconductive at 125K which is within the range of liquid nitrogen
cooling of 90K. Copper is biologically essential that is present in
various metalloproteins required for the survival of plants and animals.

Element 30, zinc, Zn, is a bluish-white metal.  Zinc is a biologically
essential trace element for the growth of animals, a zinc deficiency
requires 5¯% more food to gain the same weight.  Zinc oxide has unusual
electrical, thermal, optical, and solid-state properties. An alloy of
zinc-aluminum exhibits superplasticity.  Zinc is used to galvanize
other metals such as iron to prevent corrosion.  Zn is superconductive
below 0.85 K.

Element 31, gallium, Ga, is a soft, silvery-white metal.  Gallium is
unusual for its low melting point, it expands upon solidification one
of the few metals that expands as it freezes, as do nonmetals and most
gases.  Gallium, cesium, and mercury are the only three metals that are
liquid at room temperature.  Gallium is unique in that it has the
largest liquid range 303K to 2693K  of any element.  Main use of
gallium is the electronic industry in such compounds as GaAs
semiconductors; gallium transistors. Gallium is used for doping in
solid-state devices.

Element 8, oxygen, O, is a colorless, odorless, tasteless gas. Atoms of
oxygen are some of the atoms which forms the basis of all life for it
is part of the DNA molecule.   Oxygen is the most common element found
on the Earth’s surface composing about 49% by weight and it forms about
21% of the Earth’s atmosphere by volume.  The human body is about 2/3
oxygen by mass. Water is 88.8% by mass oxygen. A thousand atoms of
"average" seawater (3.5% NaCl by mass) would contain about 330.9 atoms
of O, 661.7 atoms of H, and 3.7 atoms each of Na and Cl. Oxygen is
essential for respiration for all animals, and restored back to the air
by plants. After 5 minutes without oxygen our life would end.  Oxygen
is essential for all combustion.  Ozone which is O3 is of vital
importance in preventing harmful ultraviolet rays of the Sun from
reaching Earth.
